Converting GIF to MP4, explained
GIF is a spectacularly inefficient way to ship animation — 256 colors and no real compression. The same clip as H.264 MP4 is routinely 80–95% smaller and plays smoother. This converter decodes every GIF frame with its original timing and re-encodes them through your browser's hardware-accelerated video encoder (WebCodecs), producing a standard MP4 that drops into <video> tags, chats, and social uploads.
The per-card progress bar tracks frames as they encode — long GIFs take a few seconds, which beats any upload-convert-download round trip and keeps the clip on your machine throughout.
What's inside the MP4, and why it plays everywhere
The file is H.264 Baseline profile (avc1.42001f) at a 4 Mbps target, with a keyframe every 30 frames and the index placed at the front so playback starts before the download finishes. Baseline is deliberately conservative: it is the profile that old Android phones, embedded players, Slack, Discord and social platforms accept without transcoding. Each GIF frame keeps its own delay; frames with no delay set get 100 ms, matching how browsers treat them. Dimensions are rounded down to even numbers because H.264 requires it, so a 301×201 GIF becomes 300×200. The 4 Mbps ceiling means the MP4 can't exceed roughly 0.5 MB per second of animation, and simple clips land well under it.
Three things do not carry over. Transparency: H.264 has no alpha channel, so transparent regions of a GIF become black in the video — stickers and cut-out animations should stay GIF or become animated WebP. Audio: there is none, and there never was. Browser choice: the pipeline needs WebCodecs' VideoEncoder and ImageDecoder, which currently means Chrome, Edge or another Chromium browser; the resulting MP4 plays everywhere, the conversion just has to happen there. Long GIFs with hundreds of frames take a few seconds and the card counts frames as it goes; the output keeps the GIF's name with an .mp4 extension.

Frequently asked questions
Everything you need to know about the GIF to MP4.
01Can I convert a GIF with transparency, or a very long one?
Transparency does not survive — H.264 has no alpha channel, so transparent regions become black; keep stickers and cut-outs as GIF or animated WebP. Length is limited only by browser memory: each frame is decoded and encoded in turn, the card counts frames as it goes, and a GIF with several hundred frames takes a few seconds. Frames with no delay set get 100 ms, matching browser playback.
02Will the MP4 loop and autoplay like my GIF did?
That's playback configuration, not file content: use <video autoplay loop muted playsinline> and the MP4 behaves exactly like a GIF — at a tenth of the bandwidth. Social platforms apply loop automatically.
03Which browsers support GIF to MP4 conversion?
The conversion uses WebCodecs (the browser's native video encoder): Chrome and Edge fully support it, Safari and Firefox are still rolling encoding out. If your browser can't, you'll get a clear message instead of a broken file.
