Convert an animated GIF to MP4 for smaller files, smoother playback, and uploads that don't get rejected.
Animated GIFs are huge - often 5 to 10 times the size of an equivalent MP4 at worse quality. Every modern messaging platform, social network, and CMS prefers MP4: smaller files, better quality, real audio support (even if your GIF is silent). Converting a GIF to MP4 is the fastest single change you can make to reduce a video asset's bandwidth bill.
Conversion uses our FFmpeg wasm engine in your browser - it understands GIF frames and re-encodes them as an H.264 MP4 with a fast-start moov atom for instant playback. The wasm engine downloads ~22 MB on first use (cached after). Expect the output to be 80-90% smaller than the source GIF at visually identical quality.
Animated GIF is the classic short-loop image format. Plays in every browser and chat app, but is heavy and lossy compared to modern video formats like MP4 or WebM.
MP4 is the most widely supported video container, based on the ISO Base Media File Format. It can carry H.264, H.265 and AV1 video with AAC, MP3, or Opus audio.
