GIF to video (MP4)

Convert an animated GIF into a small, shareable MP4. Everything runs in your browser.

How GIF to video (MP4) works

Convert an animated GIF into a compact MP4 video with ffmpeg WebAssembly. It re-encodes the GIF frames into H.264, which typically produces a file five to twenty times smaller than the original GIF while looking sharper, because MP4 is not limited to 256 colours.

Speed depends on frame count and your hardware, but most GIFs finish in a few seconds. The resulting MP4 plays natively in every modern browser and social platform, though looping then depends on the player rather than being baked into the file.

Frequently asked questions

Are my files uploaded to a server?

No. Your GIF is re-encoded into an H.264 MP4 by ffmpeg compiled to WebAssembly, inside this browser tab, the GIF is read into memory on your own device, its frames are encoded to H.264 (yuv420p) there, and the smaller MP4 is offered as a local download. Nothing reaches Sunasty or any third party. Open your browser's DevTools, go to the Network tab and watch: no request carries your file.

Why convert a GIF to MP4 instead of keeping the GIF?

MP4 (H.264) supports millions of colours, compresses far more efficiently, and plays in every modern browser and social network. The video file is typically five to twenty times smaller than the equivalent GIF, loads faster, and looks noticeably sharper, especially on footage with gradients or many colours.

Will the output MP4 loop like the original GIF?

The file itself does not embed a loop instruction the way GIF does. Whether it loops depends on the player: browsers and most social platforms loop short videos automatically, but standalone video players may play it only once. If you need guaranteed looping you can set it in the player or embed it with an HTML loop attribute.

Does it work offline?

Yes, once the page and the ffmpeg engine have loaded. The engine is sizeable and is fetched on first use, but after that the GIF-to-video conversion runs locally on your device without any internet connection.
