OpenOffice Impress is chock-full of all the features you need to build a great presentation. A simple wizard can walk you through setting up the initial backgrounds, slide design, and transition effects if you’d rather not start with a blank canvas.
There are extra features that include drawing tools, animation, text effects, and multiple monitor support, plus free templates and extensions, as well as automatic spell check and support for macros.
Overall, if you're looking for a free alternative to PowerPoint, this is the program you should choose. It even supports the popular PPTX and PPS files used in MS PowerPoint.
If you’re looking for an easy to use presentation program but still with a lot of options, Kingsoft Presentation is a perfect fit. It's easy to get started and even beginners will find it easy to create a presentation.
This free presentation maker has a clean and organized layout with a tabbed interface and tons of presentation tools, all without being too cluttered or confusing to use.
Kingsoft Presentation can run a spell check across all the slides, works with Flash, supports saving to popular file types like PPT, includes free PPT templates, and can export a slideshow to a PDF.
Note: While Kingsoft Presentation is fully usable, it hasn't been updated in several years. If you're looking for something a bit newer, you can download WPS Presentation, which comes from the same creators as Kingsoft Presentation. To get it, you have to install WPS Office.
SlideDog is a bit different than these other presentation programs because it's built for presenting files rather than building and presenting.
It works by creating a playlist of media like video, images, PDFs, and PowerPoint files. The presenter can easily add all of these files to a playlist and then use SlideDog to display it in front of an audience.
SlideDog is a great way to organize a presentation if you want something more than the normal "slide after slide" look, which is how most presentation software work.
Note: SlideDog is free to use but because there's also a SlideDog Pro version, you don't have access to features like using your own background image, looping the slideshow, sharing with a live audience, and controlling your presentation from your phone.
Express Points Presentation Software has nothing near the exhaustive features that the above programs have, but it can still function well as a presentation program, especially if you've already tried the above and want a fresh look at a different program.
Options and features are organized nicely in this free presentation program and are easy to access while working. Included are templates, text formatting, master slides, transitions, image effects, and the ability to add audio.
You can insert audio from a microphone directly into a slide, open Microsoft PowerPoint’s PPTX files, and auto save presentation files as often as every minute.
Apple Keynote is a free presentation software app for iOS and Mac users that allows for easy collaboration so the whole team can easily work together on creating that next presentation.
There are themes, slide transitions, object effects, text effects, and a whole handful of other tools in Apple Keynote.
Apple Keynote supports opening and saving to MS PowerPoint formats (PPTX and PPT). You can also export your Keynote presentation to PDF, a movie file, HTML, and an image file format.

Other Presentation Making Resources
You may also want to consider a free online presentation maker, which will allow you to work on your PowerPoint from anywhere. Since they run in your web browser, you don't have to download anything to your computer to make them work.
If you're only looking to view or present a slideshow, and not make any changes, consider using the free PowerPoint Viewer. It's a really simple program from Microsoft that does just as it seems: it lets you open a presentation file but not do any editing to it.
You can add more interest to your presentation with presentation templates and presentation backgrounds. When you add these items to your presentation, you can make it really unique and relevant for the topic.
You also might want to consider downloading a free alternative to Microsoft Office, many of which include more than just a presentation creator. They not only provide a way to replace PowerPoint with a free tool but also Word, Excel, and Access.
