About this tool
Animated GIFs are heavy: a 10-second clip that is 8 MB as a GIF is often under 500 KB as an MP4 with no visible difference. Twitter/X, Reddit, and most websites quietly convert GIFs to video for exactly this reason. This tool does the same conversion locally, producing an H.264 MP4 that plays in any browser, phone, or video editor.
Odd dimensions are rounded to even numbers (a requirement of H.264) and the result is optimized for instant playback on the web. If you need the video to keep looping, most players and embed codes have a loop option; the MP4 itself contains one pass of the animation.
How to use it
- Drop your GIF files into the box above, or click to browse. Nothing is uploaded.
- Click the button and wait a moment.
- Download the results individually or all at once as a ZIP.
Questions
Will the MP4 loop like the GIF?
The file contains one pass of the animation. Use the loop attribute or setting in your player or embed to repeat it.
Why is the MP4 so much smaller?
Video codecs only store the differences between frames, while a GIF stores each frame as a full image with a 256-color palette.
Does the MP4 have sound?
No. GIFs have no audio, so the MP4 has no audio track.
Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
