Free online PPTX to MOV converter

Some video editors and Apple-oriented workflows expect a QuickTime .mov file rather than a PowerPoint deck. Converting the slides to video makes them playable without presentation software, but animations and audio require a renderer that supports them.

What the PPTX format is

.pptx is the Office Open XML presentation format. It stores slides, text, images, layouts, and presentation effects; Microsoft PowerPoint, LibreOffice Impress, and Apple Keynote can create or open it. PPTX files are commonly used for editable slide decks and presentations.

What the MOV format is

.mov is a video container developed for QuickTime. It can hold video and audio encoded with different codecs, including H.264 and ProRes. Choose MOV when a video editor, playback system, or delivery specification requires a QuickTime file; the extension alone does not determine video quality or compatibility.

How to convert PPTX to MOV

Online on 101convert.com

1. Upload the PPTX file or select several files for batch conversion. The page shows the per-file size limit.
2. Set show each page for to the desired slide duration.
3. Convert the files and download the resulting MOV video or videos.

Offline with desktop software

LibreOffice Impress and FFmpeg: This free workflow works on Linux, Windows, and macOS with LibreOffice, Poppler’s pdftoppm, and FFmpeg installed. It renders slides as still images, so it does not retain PowerPoint animations, transitions, or embedded audio.

1. Export the deck to PDF: File → Export As → Export as PDF. Save it as presentation.pdf.
2. In a terminal, rasterize the PDF pages: pdftoppm -png -r 150 presentation.pdf slide. This creates files such as slide-1.png.
3. Create a video with five seconds per slide: ffmpeg -framerate 1/5 -i slide-%d.png -c:v libx264 -pix_fmt yuv420p -r 30 -movflags +faststart presentation.mov. Change 1/5 to another duration if needed.

Microsoft PowerPoint and FFmpeg: PowerPoint for Windows and macOS can render the deck as an MP4, including supported animations and recorded timings. Use File → Export → Create a Video on Windows, or File → Export on Mac, and save the video as presentation.mp4. Then remux it to MOV without re-encoding: ffmpeg -i presentation.mp4 -c copy -movflags +faststart presentation.mov.

Quality and compatibility

The PowerPoint workflow preserves the quality of the exported video during remuxing because -c copy does not recompress it. The resulting MOV still depends on its codecs: H.264 video with AAC audio is broadly supported, while editing applications may prefer ProRes. The LibreOffice workflow produces silent, timed still slides and cannot reproduce effects or media from the original presentation.
