Convert GIF to MP4
Turn an animated GIF into a silent MP4 video that is usually much smaller and plays more reliably in modern apps, browsers, and feeds.

Animated GIFs are easy to paste but inefficient: they often take more bandwidth than an equivalent video and can behave poorly in autoplay or mobile playback surfaces. MP4 is the practical delivery format when a looping animation should act like video.
This converter decodes the GIF frames in the browser and writes H.264 MP4 output with browser-friendly pixel format settings. The result is still silent because the source GIF has no audio track.
Odd GIF dimensions can trip H.264 encoders, so the conversion scales dimensions down to even pixel counts when needed. The ffmpeg.wasm engine loads once from this site at about 31 MB, then the GIF stays local while MP4 encoding runs.
Does this upload my files?
No. Everything on this page runs locally in your browser, so your files are never uploaded to a server. Close the tab and nothing is left behind. It even keeps working if you go offline after the page loads.

FAQ
Why convert GIF to MP4?
MP4 usually makes a much smaller file than GIF and is accepted by more players, mobile apps, and social feeds.
Will the MP4 have sound?
No. Animated GIFs do not contain audio, so the converted MP4 is a silent video.
Why can the MP4 dimensions change by one pixel?
H.264 needs even frame dimensions, so odd-width or odd-height GIFs are scaled down to the nearest even size before encoding.
