Why convert GIF to MP4?

MP4 (H.264) is far more efficient than GIF. A typical 5 MB animated GIF can become a 100–300 KB MP4 — an 80–95% size reduction — while delivering better color accuracy and smoother playback. Browsers and mobile devices are also optimized for video decoding, making MP4 playback faster and less CPU-intensive.

Why can't this tool convert GIF to MP4 directly in the browser?

True GIF-to-MP4 encoding requires H.264/H.265 video encoding, which is not available natively in browsers. WebAssembly builds of FFmpeg exist but are very large (20+ MB downloads) and slow for most users. The FFmpeg command-line tool, HandBrake, or a trusted online converter handles this instantly on any hardware.

What FFmpeg command should I use?

The recommended command is: ffmpeg -i input.gif -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libx264 -pix_fmt yuv420p -movflags +faststart output.mp4. The scale filter ensures dimensions are even (required by H.264). The -pix_fmt yuv420p flag ensures the widest browser compatibility.

Will the MP4 loop like the original GIF?

By default, MP4 does not loop. To loop in a web page use the HTML video tag with the loop attribute: . This is the recommended way to use MP4 as a GIF replacement on websites.

Is my GIF file uploaded anywhere?

No. The GIF analyzer on this page reads the file entirely in your browser using the FileReader API. Your file data is never sent to any server.

Does this work for large GIF files?

The in-browser analyzer handles GIF files up to about 50 MB comfortably. For the actual MP4 conversion, FFmpeg handles files of any size limited only by your disk space.
