A video of a presentation plays anywhere: on YouTube or a website, in a chat or an email, on a TV or a screen in a shop window, or on a phone that has no PowerPoint. PowerPoint's own Export to video needs desktop PowerPoint, and most online converters upload the deck and stamp a watermark. This page draws each slide with the site's PowerPoint Viewer, takes a picture of it, and makes the pictures into an MP4 with the same encoder as the Slideshow Maker. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.
Be clear about what you get: each slide is a still picture, shown for its seconds. The deck's own animations (text flying in, builds) and slide transitions are not played; each slide appears as it finally looks, with a plain cut or a crossfade between slides. Recorded narration, videos and sounds placed on slides are not included, and the video has no sound track.
- Are animations, transitions and narration kept?
- No. Each slide is a still picture of how it looks once all its animations have finished, so text that flies in is simply there. The deck's transitions are replaced by a crossfade or a cut, whichever you choose. Recorded narration, slide timings saved in the deck, and videos or sounds placed on slides are not included; a video on a slide shows as a dark box marked Video. For those, use File, Export, Create a Video in desktop PowerPoint.
- How long is each slide shown?
- Five seconds unless you change it; any time from 1 second to 10 minutes. Open Change the time of single slides to give one slide longer, say 20 seconds for a table people need to read, and leave the others on the main time. The button shows the video's total length before you make it.
- Will the video have sound?
- No, the MP4 has a picture track only. To put music under it, open the saved video in Add Music to Video; to build a video of pictures with music from the start, the Slideshow Maker takes slide pictures saved by PowerPoint to JPG.
- Will the slides look as they do in PowerPoint?
- Close for most decks: text with its fonts and colours, shapes, pictures, tables, charts and backgrounds. A font this device does not have is replaced by a similar one, pictures in EMF or WMF format appear as a labelled box, and some chart types are drawn more simply; the page lists any of these under the file before you make the video.
- Can I upload the MP4 to YouTube or play it on a TV?
- Yes. It is an ordinary H.264 MP4, the format YouTube, Vimeo, Facebook, Teams, Google Slides, phones, smart TVs and USB players all take. 1080p suits YouTube and big screens; 720p makes a smaller file for email or chat.
- Can I convert an old .ppt file to video?
- Yes. PowerPoint 97-2003 files (.ppt, .pps, .pot) are read by the site's own reader and drawn the same way as .pptx. Files from PowerPoint 95 and earlier are not read, and neither are presentations protected with a password to open.
- Is my presentation uploaded to make the video?
- No. The slides are drawn and the video is encoded by your browser in this tab, on your device; nothing is sent to this site or anywhere else. That is also why a long deck at 1080p takes a while on an older phone.
