GIF to MP4 Converter
Turn an animated GIF into an MP4 that plays everywhere and is usually far smaller than the original. No upload, works offline, no watermark. Your file is converted on your device.
Runs entirely in your browser — your GIF is never uploaded.
- No upload Your video never leaves your device — it is processed locally.
- Works offline After the first load it runs with no internet connection.
- No size or daily limits No file caps, no paywalls — only your device memory.
- Private & safe Skip sketchy upload sites; nothing is sent to a server.
How it works
The conversion is handled by ffmpeg compiled to WebAssembly and run inside your
browser. It decodes the animated GIF, ensures the dimensions are even with
scale=trunc(iw/2)*2:trunc(ih/2)*2 (H.264 requires even width and height), sets a
broadly compatible pixel format with -pix_fmt yuv420p, and encodes the video as
H.264 (libx264) at a quality of -crf 23. It writes the file with
-movflags +faststart so it begins playing quickly. Because GIFs have no sound, audio
is dropped with -an. Everything runs on your device, so the GIF is never uploaded.
How to convert a GIF to MP4
- Choose an animated GIF with the drop zone above, or drag one onto it.
- Press Convert to MP4 and watch the on-device progress bar.
- Wait a moment — GIFs are small, so this is usually quick.
- Click Download to save your MP4.
Conversion runs on your device. Most GIFs are tiny and finish in seconds; a very long or large-dimension GIF takes a little more time and memory.
Why convert locally instead of on an upload site
Online GIF-to-MP4 converters upload your file to a server, which is slower, hands it to a third party, and sometimes adds a watermark or a size cap. Converting in your browser removes the upload step, keeps the file private, and adds nothing to the output. It also avoids the safety concerns around free file sites — in March 2025 the FBI warned that some free online converter sites were being used to distribute malware, so on-device conversion is the safer choice.
| Local (this site) | Typical cloud tool | |
|---|---|---|
| Upload required | No | Usually |
| File-size caps | None (device memory) | Common |
| Works offline | Yes, after first load | No |
| Files stay private | Yes — never sent | Sent to a server |
Common uses
Shrinking a heavy GIF so it loads faster on a web page, converting a GIF for a platform that prefers or requires video, saving data and battery for viewers by serving an MP4 instead of a GIF, or preparing a looping clip for a messaging app. For the reverse — turning a video clip into a GIF — use the Video to GIF tool.

Frequently asked questions
Why convert a GIF to MP4 at all?
GIF is an old, inefficient format: it is limited to 256 colours and stores frames with weak compression, so animated GIFs are often several times larger than an equivalent MP4. Converting to MP4 (H.264) usually shrinks the file dramatically while keeping the motion smooth, and MP4 is supported natively by virtually every browser, phone and social platform. It also lets the clip use full colour instead of 256.
Is my GIF uploaded to convert it?
No. The conversion runs locally with ffmpeg compiled to WebAssembly. Your GIF is read into the browser, converted on your device, and the MP4 is written there for download. Nothing is sent to a server and no copy is stored online.
How much smaller will the MP4 be?
It depends on the GIF, but a reduction of anywhere from 50% to over 90% is common, especially for longer or larger animations. GIFs waste space on every frame, while H.264 only stores what changes between frames, so smooth or repetitive motion compresses extremely well.
Will the MP4 still loop and autoplay like the GIF?
On most platforms, yes. Social networks and messaging apps that accept short MP4s typically autoplay and loop them just like a GIF, often using less data and battery. If you embed it yourself in a web page, add the loop, autoplay and muted attributes to the video element to reproduce GIF-style behaviour.
Does the MP4 have sound?
No. GIFs have no audio, so the converted MP4 is silent by design — the tool explicitly drops any audio stream. That keeps the file small and matches how the original GIF behaved.
Does it work offline?
Yes. The site is a Progressive Web App, so it works without a connection after the first visit, and the ffmpeg engine is cached after its one-time download so conversions keep working offline.
