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.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
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.
Frequently asked 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 this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
