GIF to MP4
Processed locally in your browser — nothing is uploaded.
Quick answer
GIF to MP4 converts an animated GIF into an MP4 video, which is dramatically smaller for the same motion and plays inline on social media where GIFs often will not autoplay. It encodes with H.264 using `yuv420p` pixel format for maximum device compatibility. It runs in your browser on the ~10MB ffmpeg engine, downloaded once and cached; your GIF is never uploaded anywhere.
How to gif to mp4
Add your GIF
Drop an animated .gif onto the drop zone. Static, single-frame GIFs convert too — they just produce a one-frame video.
Convert to MP4
The tool re-encodes the frames as H.264 video in an MP4 container, using the widely-compatible yuv420p pixel format.
Download the MP4
Save the .mp4. It will typically be a small fraction of the GIF’s size and play inline on phones, chat apps and social platforms.
Why convert a GIF to MP4 at all?
GIFs are heavy and, ironically, often will not autoplay in the places people most want them. MP4 with H.264 uses real motion compression, so it stores the same animation in far fewer bytes, and every phone, browser and messaging app plays it inline. Converting a chunky GIF to MP4 routinely cuts the file size by 80–90% with no visible loss.
| Property | Animated GIF | MP4 (H.264) |
|---|---|---|
| Compression | Per-frame, no motion coding | Inter-frame motion compression |
| File size | Large | Typically 80–90% smaller |
| Colours | Max 256 per frame | Full colour |
| Audio | None | Supported (though a GIF has none to carry) |
| Autoplay inline on social | Often blocked or re-encoded | Native, smooth |
What is yuv420p and why does it matter?
yuv420p is a pixel format — a way of storing colour where brightness is kept at full resolution but colour is subsampled. It is the format hardware video decoders in phones, browsers and TVs are built to play. Some encoders default to yuv444p for a GIF’s sharp graphics, but that produces MP4s that show a black screen or fail to play on many devices. This tool encodes to yuv420p specifically so the result plays everywhere.
Can you go back to GIF later?
Yes. If a destination truly needs a GIF — an old forum, an email signature, a true auto-looping image — convert the MP4 back with Video to GIF. Round-tripping is lossy on the GIF leg because of the 256-colour limit, so keep the MP4 as your master. To shrink the MP4 further, run Compress Video; to change its container to WebM, use the Video Converter.
Is my GIF uploaded during conversion?
No. The conversion happens entirely in your browser via the WebAssembly ffmpeg engine. Your GIF is read locally and the MP4 is built locally — nothing is transmitted. Verify it in DevTools → Network: aside from the one-time engine download, converting a file sends no upload request.
Your files never leave your device
Processed locally in your browser — nothing is uploaded. You can verify it yourself: open your browser’s developer tools, watch the Network tab, and use the tool — no upload request is ever made.
Frequently asked questions
How much smaller will the MP4 be?
For a typical animated GIF, expect an 80–90% reduction. MP4’s motion compression is far more efficient than GIF’s per-frame storage, so the savings are large with no visible quality loss.
Will the MP4 play on iPhones and inside chat apps?
Yes. The tool encodes H.264 with the yuv420p pixel format, which is exactly what mobile decoders and messaging apps expect, so the video plays inline everywhere.
My converted MP4 shows a black screen elsewhere — why?
That is the classic symptom of a yuv444p MP4 on a device that only decodes yuv420p. This tool uses yuv420p specifically to avoid it, so files from here should not have that problem.
Does the MP4 loop like the GIF did?
The MP4 contains the same frames but looping is up to the player. Social platforms loop short MP4s automatically; in a plain HTML5 video add the loop attribute.
Will it keep the animation speed?
Yes. The GIF’s frame timing is read and preserved, so the MP4 plays at the same speed as the original animation.
Can I convert a static GIF?
Yes, though the result is a single-frame video. GIF to MP4 is meant for animated GIFs; for a still image, an image tool is the better fit.
