Either way, you probably don't have much to spend on a web presentation software tool. At some point or another, most of us need to create a slideshow. 

Virtual Presentation Illustration

If you need a tool to help you create web presentations, but you're on a limited budget, you may think you're out of luck. Fortunately, there are quite a few good free presentation tools for you to consider.

What to Look for in Free Online Presentation Software

It's important to use a good web presentation tool when showcasing it. Many free online presentation tools have all the features you need. Create a top-notch web presentation with presentation websites for free .

Here are some things to look for when selecting online presentation software:

  • Ease-of-use. You don't want to spend hours and hours learning how to use the web presentation tool. Good online presentation software should be easy to learn and have plenty of training resources available.
  • Import/export features. Your presentation software tool should be compatible with popular file formats. Also, keep in mind that at some point you may want to export your presentation into another tool.
  • Real-time collaboration . Teamwork has become increasingly important in today's professional environment. With the right web-based tool, you and a teammate can work together on a presentation project.
  • Cloud access and storage. It used to be that when you were away from your computer, you couldn't work on your project until you came back. With a cloud-based tool, that's no longer a problem. Access your work anywhere there's an Internet connection.
  • Audio/video capabilities. Multi-media has become the norm for slideshows. If you want your presentation to really stand out, consider adding an audio or video component.
  • Good technical support. What are you going to do if something goes wrong while you're creating your presentation? Look for quality support resources such as third-party tutorials and a strong online help section

When choosing an online presentation software tool keep in mind your future needs. Consider starting with presentation websites for free. Then work with the premium version of the presentation software tool of your choice.

I Quit Writing Formulas in Google Sheets—AI Does It for Me

How i organize my to-do lists in apple reminders, count cells with specific text in excel using the countif formula.

Microsoft PowerPoint has been around for a long while and so far it has served users well. However, because it's a paid program, not everyone can afford it.

Thankfully, there are many options available for users who want the functionality of Microsoft PowerPoint in a free-to-use package. In fact, some of them don't even require any downloads and are completely web-based.

1. Google Slides

Google Slides editing screen

By far the most popular PowerPoint alternative out there, Google Slides shines when it comes to collaboration. Multiple people can work simultaneously on a presentation and add new slides.

This is further strengthened by its availability. Google Slides works on your web browser and has apps for both iOS and Android.

Additionally, Google Slides keeps a record of all the changes users have made to a presentation, and you can easily restore your slideshow to a previous version. While anyone with a Gmail account can use Google Slides, G Suite users get added data protection.

Compared to PowerPoint, the number of templates, animation forms, and fonts is somewhat lacking. However, businesses tend to overlook these shortcomings on a day-to-day basis.

Canva Presentation maker.

While Canva is primarily known as a photo editor and design tool, it is also a competent MS PowerPoint alternative.

One of Canva's main strengths is its ease of use. There are many beginner tutorial videos on the website if users do not understand something. Complete beginners can easily navigate through the minimalistic interface.

With the free version of Canva, you get access to over 8000+ presentation templates that exponentially speed up your workflow. Additionally, Canva still remains one of the easiest services to create infographics and charts in.

The only limiting thing with Canva is that it offers a basic set of tools and transitions at users' disposal. It's apparent that the company places more focus on photo editing and design aspect than anything else.

Prezi presentation editing screen.

The Prezi presentation format is unique in the way that it lets you view slides. Instead of addressing multiple elements at once, Prezi gives viewers a single canvas that allows them to zoom in on different presentation parts. This provides a much more immersive experience.

Similar to Google Slides, Prezi supports the real-time collaboration of up to 10 users. Users can also add comments to indicate changes or report missing information. Prezi works on any modern web browser, and there are Android and iOS apps available as well.

Related: Powerful Google Chrome PDF Extensions and Apps

The Prezi software also has an analytics feature that helps users optimize their presentation by showing them which slides were the most viewed as well as which ones were skipped.

Even though the basic version of Prezi is free to use, it doesn't allow users to control the privacy of their presentation, which could be a dealbreaker for many. Additionally, due to the way Prezi works, there is a steep learning curve associated with it.

4. WPS Office Free

WPS Office Web Presentation maker

WPS Office is the closest alternative to PowerPoint when it comes to functionality and user interface. Plus, unlike the other web-based services on this list, you don't always need an active internet connection to use it.

With its complete support for PowerPoint files, users can edit existing PowerPoint documents with ease in WPS Office. They can also embed videos and animate individual objects, just like in Microsoft PowerPoint. It also offers many templates, so users can pick their favorite.

However, users should keep in mind that while the software is free, it is supported by ads, which may be a bit intrusive at times. In addition to this, collaboration is less straightforward than with Google Slides.

WPS Office is available across all major platforms such as Windows, macOS, Linux. iOS, and Android. There is a web-based version available as well. Alternatively, you can check out this handy guide to smoothen your transition to WPS Office from Microsoft .

Xtensio presentation maker web app.

Xtensio is one of the best options for business users. It has many templates available regarding various organization sections, such as marketing, UX design, etc.

With Xtensio's easy-to-use interface, even newbies can create professional-looking reports and presentations. Additionally, they offer even greater flexibility in terms of design. You can edit each object in a template to suit your specific needs.

But it does have some shortcomings. For one thing, users cannot export their presentations in PowerPoint format. Additionally, the free version supports only one user at a time with a storage space of 1MB.

6. LibreOffice

LibreOffice Impress Presentation Software editing screen

LibreOffice is open-source presentation software that does everything PowerPoint can do. Although it lacks functionality such as OneDrive Integration, its PowerPoint-like functionality more than makes up for it.

LibreOffice has its share of useful features, such as the ability to import Keynote files. In addition, LibreOffice has a vast collection of free templates that users can use to create their presentations.

If that's not enough, you can download additional templates from LibreOffice's online repository. LibreOffice is available across Windows, macOS, and Linux.

7. Zoho Show

Zoho Show presentation maker

There are several reasons to use Zoho Show for your next presentation. It's a great presentation tool that's similar to Google Slides, but even better. Users can also import and edit all their PowerPoint files in the online tool.

Users can create tables, infographics, and data charts within Zoho Show itself. In addition to this, the service also has in-built Google Image Search functionality that lets you search and insert images quickly.

Related: Tools to Give an Online Presentation From Anywhere

Additionally, Zoho Show supports collaboration in real-time and multiple users can edit presentations. Although there's not much to complain about in Zoho Show, many users would like to have more options when it comes to templates and animations.

Worthy PowerPoint Alternatives

Essentially, all these tools and services function the same way as PowerPoint without the cost. Furthermore, the web-based alternatives are more advanced such as automatic saving and cloud storage.

Despite this, PowerPoint remains the front-runner when it comes to presentation software. As such, it is important for users to know how to make the best out of its features.

3 open source tools to make your presentations pop

IRC screenshot

Opensource.com

Love them or hate them, presentations are a major part of life in both academia and business. Traditionally, creating a presentation meant using Microsoft's PowerPoint, but Apple's Keynote and LibreOffice/OpenOffice.org's Impress are solid alternatives. The problem with all those applications (aside from the closed source nature of the first two) is that you need those applications installed in order to view the presentations you've created. You can try your luck opening the file in Google Drive or the like, but your success will vary.

In recent years, web frameworks designed for creating presentations have proliferated. These take advantage of HTML5, CSS3, and JavaScript to create presentations that display in just about any modern web browser. And, as an added bonus, presentation designers remains in complete control of their presentations. They need not worry about file compatibility or being locked into a particular web-based service. Because these presentation frameworks are open source, they can be extended and enhanced in any way you wish—though to be fair, writing HTML, CSS, and JavaScript is a little more complicated than just using PowerPoint, Keynote, or Impress.

One of the most interesting presentation frameworks is impress.js, which aims to move presentations beyond the standard slide deck. Below, I'll introduce you to impress.js and two tools that make it easy to create impress.js presentations.

Impress.js is a JavaScript presentation framework developed by Bartek Szopka. Inspired by Prezi , it makes use of CCS3 transformations to provide a presentation experience that goes way beyond the traditional slide deck. Using impress.js for presentations allows speakers to wow their audiences with presentations that slide, rotate, and zoom in three dimensions.

Being based on standard web technologies (HTML, CSS, and JavaScript) means that impress.js does not lock users into using a particular application or web-based service to create presentations. Because it is released under the MIT and GPLv2+ licenses, if impress.js does not work the way you'd like, you have the freedom to change it yourself. However, unlike some other open source JavaScript presentation frameworks, impress.js requires a very modern web browser to view the presentations. It is designed to take full advantage of up-to-date web technologies. Legacy browser support is not a development priority. But recent releases of Chrome, Firefox, Safari, and Internet Explorer should work just fine with impress.js.

Creating an impress.js presentation is no easy task, even for someone with decent HTML and CSS skills. The basic markup is easy to understand, but impress.js presentations can be very complex and require a lot of thought and planning. There is no default theme, so you'll have to design the look and feel of your presentation yourself. And the flow of your presentation is entirely up to you, so you'll have to plan how each slide will transition to the next and the layout of the slides' relative positions in the canvas. Creating an impress.js presentation from scratch can be a lot of work, but the results can be impressive. A selection of demos and examples are available to provide inspiration and guidance, and there are tutorials for those who want to dig deeper and learn more.

If creating an impress.js presentation from scratch is too complicated for you, there are tools to make creating impress.js presentations easier. The two listed below have different strengths and weaknesses. Give them both a try, and see if one works for you.

Hovercraft simplifies the creation of impress.js presentations by allowing you to create presentations using reStructedText markup. Instead of having to write HTML markup while crafting a presentation, you can focus on just writing the text. You can move things around and change things without having to mess with complicated markup. For example, the following text creates a slide that is five times larger than the previous slide and rotated 90 degrees.

Creating an impress.js presentation using Hovercraft greatly simplifies the process and enhances impress.js. Hovercraft supports four different methods for positing slides in a presentation. If you specify no positing in your markup, you end up with a traditional slide-to-the-left slide show. If you want something a little fancier, you can use relative positioning and slides are positioned based on the offset you specify relative to the previous slide. This method allows you to easily insert a new slide in the middle of a presentation and have all the following slides readjust their positions. If you want total control, you can use absolute positioning, which allows you to specify the precise coordinates of a slide. And finally, you can specify a SVG path for the presentation to follow. According to Hovercraft's documentation, SVG layouts are "a bit fiddly to use," but having such precise control over the layout can result in some pretty impressive slide shows. In addition, Hovercraft supports syntax highlighting for any source code you want to include in your presentation, and it adds a presenter screen with timer and notes. When you're done writing your presentation (or want to test what you have written so far), a very simple command converts the reStructuredText file into an HTML presentation:

Despite Hovercraft's strengths, it still requires the user to be fairly CSS savvy. The default Hovercraft theme is extremely spartan, so you'll still need to stylize your presentation if you want anything fancier than plain black text on a white background. Adding CSS to a presentation is not complicated, but it is not as easy as selecting a new presentation theme in PowerPoint.

You can read Hovercraft's documentation to learn more.

Hovercraft was created by Lennart Regebro and is licensed under a Creative Commons CC0 1.0 Universal license.

If you'd like a tool that works more like traditional presentation software, Strut is the tool for you. Strut is a web-based application that provides the traditional slide sorter and editing tools. The graphical tools let you add text, images, videos, websites, and pre-designed shapes to your slides. You can also easily change the color of the slides' backgrounds and the surface (the backdrop in front of which the slides appear) for the entire presentation all at once, or on a slide-by-slide basis. Strut also supports adding text to slides using Markdown . And for power users, you can apply custom CSS classes to objects and write custom CSS rules from inside Strut. Once you have your slides designed, you can switch to Overview mode and graphically layout your slides. You just drag around the slides and enter values for depth, rotation, and scale. In addition to creating impress.js presentations, Strut can also create presentations using the bespoke.js framework.

Strut is very nice, but it does still have a few rough edges. Users will encounter the occasional bug, and the project's to-do list is somewhat long (though that is not a major issue). The project has followed the "release early, release often" maxim, and anyone who wishes to can help make the project better by contributing on GitHub .

Give Strut a try using the editor on the project's site , or download the source from GitHub and run it locally (or on a server). You'll need Node.js's npm and Grunt to install the dependencies and build Strut.

Strut's creator, Matthew Crinklaw-Vogt, has released the application under the GNU Affero General Public License, Version 3 .

6 Open Source Presentation Tools

As a software developer, PowerPoint, Keynote, or Google Sheets quickly become boring for presentations. You want something different, you want to create the presentation with Markdown files, HTML, or JavaScript. There are some open source solutions for that, like reveal.js , mdx-deck , Spectacle , remark , webslides or impress.js . Each solution allows you to create presentations yourself in minutes, push them to GitHub, and share them with your audience.

Personally, I have tried mdx-deck and Impress.js in the past. Which one do you use?

  • With React Icons it's a breeze to add Bootstrap, Feather, Font Awesome, Hero-, VS Code, css.gg , and more popular icons to your React app.
  • Wouldn't it be great if you didn't have to change anything in your Docker container image and could still shrink it by a factor of up to 30x? That's what docker-slim promises!
  • Static site generators are becoming more and more popular. Eleventy , a JavaScript alternative to Jekyll, promises to be another simple solution.
  • While we're on the topic of static site generators, Speedlify lets you quickly and easily create a web performance and accessibility benchmark. Here are some Eleventy benchmarks .
  • At work the other day we were discussing if and how it is possible to keep multiple React mini-apps in sync with Redux in one document. Here is a clear example that shows how it works. It's easier than you might think.
  • When I started streaming , I also looked into the topic of "virtual-cams". Not because I use it with OBS, but because I wondered if I could use OBS' output in Skype, Slack, and other apps. And lo and behold, it's actually possible on macOS as well. Thanks to the open-source solution of John Boiles and the other contributors.

Every year churches spend hundreds of millions of dollars on the software needed to operate effectively and efficiently. We believe that within the Church the talent exists to create all the software that churches need and provide it free of charge.

Changing how we handle church software can not only save a lot of money, but also bring believers together. If we use the skills within our own community, we can make the software that the Church needs without the costly expense. This way, more of our funds can go directly to the Church's mission instead of overhead. It's about working together, saving money, and focusing on what truly matters.

The best free presentation software makes it simple and easy to create professional presentations without a Microsoft subscription.

While PowerPoint is the market leader when it comes to presentation software, some people may be unwilling to subscribe to a Microsoft 365 subscription, especially if they don't expect to need to use it very often.

However, there are plenty of great alternatives to PowerPoint available for free that you can use. While these won't have the same advanced features as PowerPoint, they still offer a very competent platform to design most any presentation that you need.

To help you choose, we've listed below the best free presentation software currently available.

Google Apps

Google Workspace : Collaboration + productivity apps There are many different presentation software packages but Google Workspace formerly known as G Suite remains the original cloud office software and one of the best business office suites, offering a huge range of features and functionality that rivals can't match, especially when it comes to presentation software.

Our expert review:

Reasons to buy

Reasons to avoid.

Prezi turns the traditional approach to presentations on its head. Instead of creating slide after slide, this presentation software gives you a single giant canvas. You can add blocks of text or images, or even create miniature slides. During your presentation, you can seamlessly fly around the canvas and zoom in to look at individual chunks of content.

For how complex Prezi seems, it’s impressively simple to use the platform. The only major divergence from Microsoft PowerPoint is that you need to add animated paths from one part of the canvas to another. The tools for this are fairly straightforward, especially if you’ve ever used an animation or video editing software.

Of course, this type of presentation structure isn’t always ideal. Prezi makes it hard to visualize structured data like financials, which can make it difficult to use in business applications. Some viewers also might not appreciate the fly-around animation style that’s inherent to the presentation software.

Best free presentation software for functionality

Website screenshot for LibreOffice.

2. LibreOffice

LibreOffice is a free alternative to Microsoft Office, and it includes a Powerpoint equivalent called Impress with nearly all of the same functionality. The only big difference you’ll find between the two slideshow creation tools is the LibreOffice lacks some modern features like built-in collaboration and integration with Microsoft OneDrive.

However, Impress does have a few advantages of its own. The software can import files from Keynote, the default presentation software on Mac computers. Plus, there are hundreds of free templates that you can download for free. Even better, there’s no limit on what fonts you can use with Impress, so it’s easy to change the look of your presentation from what Powerpoint typically allows.

On the whole, LibreOffice Impress is about as close as it gets to simply replicating Microsoft Powerpoint for free.

Best free presentation software for collaboration

Website screenshot for Google Slides.

3. Google Slides

Google Slides is part of Google Workspace (formerly G Suite), and it does a nice job of matching a number of PowerPoint’s capabilities. This free presentation software supports embedding videos, creating diagrams, and adding animations to your slides. While the selection of templates is somewhat limited, you can easily import hundreds of additional templates for free or create your own.

Even better, Google Slides supports the collaboration tools users have come to expect from Google. Multiple people can work on a slideshow simultaneously, and there’s a built-in group chat so you can keep track of what everyone is doing. It’s also nice that you can play your presentation in presenter mode, which allows you to preview how it will look to your audience and rehearse timing.

The only downside to Google Slides is that bloated slideshows can experience some loading delays. Also beware that while you can move between Slides and Powerpoint, the conversion often messes with the layout of your slides.

This software offers a handful of free layouts to help you get your slideshow started, and it’s easy to customize the templates to fit your needs. There isn’t a huge variety of content elements to add to your presentation, but Canva makes up for this with a searchable library of more than 1 million images you can use.

Your Canva presentations live online, which makes it extremely easy to collaborate. You can invite colleagues to edit your slideshow (although simultaneous editing is not supported) or seamlessly share your finished presentation. However, beware that Canva can’t import presentations from Microsoft Powerpoint or export finished work to a Powerpoint-editable format.

Best free presentation software for user interface

Website screenshot for WPS Office.

5. WPS Office Free

WPS Office Free is a Microsoft Office look-alike that fully support PowerPoint files without any layout issues during import. The WPS Presentation tool has all of the same capabilities of PowerPoint, including tons of animations, slide transitions, content effects, and video embedding. The selection of included presentation templates is also very impressive for a free software.

One of the best things about this presentation software is that the user interface will feel incredibly familiar if you’re coming from Microsoft. All of the tools are displayed in a top ribbon, with your slides shown on the left side of the screen for easy navigation. It’s simple to display your presentation right from WPS Presentation, which means there’s no unexpected troubleshooting when it’s time to show off your work.

There’s not much to dislike about WPS Presentation. However, keep in mind that the software is supported by ads. Some users find the ads annoying, but they’re not overly in the way.

Best free presentation software FAQs

Which alternative to powerpoint is best for you.

When deciding which alternative to PowerPoint to download and use, first consider what your actual needs are, as sometimes free platforms may only provide basic options, so if you need to use advanced tools you may find a paid platform is much more worthwhile. Additionally, free and budget software options can sometimes prove limited when it comes to the variety of tools available, while higher-end software can really cater for every need, so do ensure you have a good idea of which features you think you may require.

How we test the best free presentation software

To test for the best free presentation software we first set up an account with the relevant software platform, whether as a download or as an online service. We then tested the service to see how the software could be used for different purposes and in different situations. The aim was to push each software platform to see how useful its basic tools were and also how easy it was to get to grips with any more advanced tools.

Top 3 open-source alternatives to PowerPoint

The presentation software PowerPoint is proprietary, and hence not so transparent and less cost-effective than some competitors. Discover the best open-source PowerPoint alternatives in this article.

Top 3 open-source alternatives to PowerPoint

ONLYOFFICE Desktop Editors

ONLYOFFICE presentation editor for desktop is a free PowerPoint alternative for Windows, Linux, and Mac. The app is open-source and you can find the code on GitHub.

With the existing functionality of ONLYOFFICE Desktop Editors, you can make creative slides and add text, objects, tables, background patterns etc. Your presentations can become even more interactive with transitions and customizable animations. The interface looks exactly the same as you have in PowerPoint, so it won’t take much time to adapt to a new application.

Plugins extend the basic functionality of the ONLYOFFICE presentation editor. For example, you can insert YouTube videos or translate text in presentations using Google or DeepL really quickly.

The core ONLYOFFICE formats for presentations are PPTX and PPT, but ODP and PPSX are also supported. Also, you can save each slide as a PNG or JPG image and use the pictures in another type of content.

ONLYOFFICE presentation editor has a special Presenter View mode, where you can add notes to highlight important parts of your speech and comfortably navigate between slides.

Unveil your creativity with the best open-source PowerPoint alternative for Windows, Linux, and Mac — ONLYOFFICE. Installation options include Snap, Flatpak, and AppImage. Also, ONLYOFFICE Desktop Editors are pre-installed on many Linux distributions .

ONLYOFFICE also provides a collaborative open-source office suite for self-hosting with text documents, spreadsheets, presentations, and fillable forms.

LibreOffice Impress

LibreOffice is another open-source alternative to PowerPoint, which allows creating, editing, and saving presentations in the ODP (OpenDocument) format.

Top 3 open-source alternatives to PowerPoint

The interface in LibreOffice is just a bit similar to what you see in Microsoft PowerPoint. You’ll need to play with the elements to get used to their location on your screen, but indeed they are positioned logically.

As for presentation features, you’re able to draw and add objects, such as diagrams, create 2D and 3D images from text with the Fontworks tool, and use animations and transitions to let objects and slides move.

LibreOffice also provides a gallery of presentation templates if you’re not sure where to start.

Calligra Stage

Developed by KDE, Calligra Stage is a powerful and free open-source alternative to PowerPoint. It allows working with various objects, such as text, charts, images, graphics.

Top 3 open-source alternatives to PowerPoint

Calligra Stage also uses the ODP (OpenDocument) format as the primary one. That means, your presentations will be displayed without distortions in other apps working with this extension, but also OOXML-based suites, such as ONLYOFFICE Docs and Microsoft 365.

This open-source presentation app is built by developers from many countries and includes all necessary features: layouts, presenter slide overview, multiple master sliders in one presentation, transitions and notes.
