Want to create a free PowerPoint presentation but don’t have Microsoft Office? Maybe this is because you are not using Windows or you just cleaned your computer. Anyhow creating PowerPoint Presentations is now possible without the need of MS Office with the free online service called 280Slides.
Update: This web service has been discontinued.
When you visit the website, you will be greeted with a welcome window, where you can either Create a new presentation, Open a saved presentation, or Import an existing presentation. It can import Outlook 2003/2007/2010 and Open Office Presentations (PPT, PPTX and ODP formats).
Once you hit Create New Presentation, you will be shown a list of themes to choose from.
Choose any theme and hit OK. The whole interface looks similar to PowerPoint presentation, you can add new slides from the left sidebar, add images, shapes, videos, text from the top bar. There are a bunch of more options that you will find such as, bring item to Front/Back, Undp/Redo, Add Notes, Fit to width, Opacity, Themes, Layouts and much more.
On the upper-right side you will find options to start slideshow, download the presentation, and share it with friends. The good part is that you can download the presentation in either PPT, PPTX, ODP or PDF format without having to register.
Registration is only required if you would like to save the presentation online.
In short, it is one heck of an awesome service to create presentations. Enjoy!
