About the GIF to MP4 Converter
This free GIF to MP4 converter turns animated GIFs into H.264 MP4 videos, which are typically a small fraction of the original GIF size while looking just as good or better. MP4 is supported everywhere — websites, phones, social platforms and messaging apps — and plays back far more smoothly than a heavy GIF.
The conversion runs in your browser via FFmpeg WebAssembly, so your GIF is never uploaded. The engine (around 30 MB) is fetched from a CDN the first time you use it and cached afterwards, which is why the first conversion takes longer.
The tool encodes with a web-friendly yuv420p pixel format and automatically pads the video to even dimensions, which H.264 requires — so the MP4 plays correctly on every device. Note that MP4 does not loop on its own the way a GIF does; add a loop attribute in your player or webpage if continuous looping matters. Files up to 100 MB are supported.

Frequently Asked Questions
Is my GIF uploaded to a server?
No. The GIF is converted in your browser with FFmpeg WebAssembly and never leaves your device. Only the engine is downloaded, once.
Why is the first conversion slow?
The first run downloads the FFmpeg core (~30 MB) from a CDN and compiles it in your browser. It is cached afterwards, so later conversions are fast.
Why is the MP4 so much smaller than the GIF?
GIF stores animation very inefficiently, while H.264 MP4 uses modern video compression. The same animation as MP4 is often just a fraction of the GIF's size, with no visible quality loss.
Will the MP4 loop automatically?
No. Unlike GIFs, MP4 does not loop by itself. Add the loop attribute to your video player or the HTML <video> tag if you need continuous looping.
Does the MP4 have sound?
No — GIFs contain no audio, so the resulting MP4 is silent. That is expected and keeps the file small.
