The most reliable source format
H.264 in an MP4 container is the one codec combination every browser ships, so MP4 sources decode everywhere — no codec roulette, no refused files.
Turn H.264 MP4 clips into shareable looping GIFs.

Overview
Convert MP4 video to GIF free online. H.264 MP4 plays in every modern browser, so frames are sampled locally — choose span, frame rate and size, then download.
MP4 is where video lives: phone cameras, screen recorders, exports from every editor. GIF is where short moments get shared: chat, comments, documentation, slides. This page is the bridge between the two, and it runs entirely in your browser.
H.264 in an MP4 container is the baseline codec combination of the web — the one every browser, phone and smart TV ships. That means the decode step of the conversion never depends on optional codecs, and a file that plays in your media player will sample here too.
No audio, no more than 256 colours per frame, no partial transparency. Gradients band, footage dithers, and files are large for what they show. Those are the format's 1987 constraints, and they are the price of playback literally everywhere.
Step by step
Drop an .mp4 file onto the upload area; its duration and resolution appear immediately.
Set the start and stop seconds around the moment you want to loop.
Pick a frame rate and output width — 10 fps at 480 px is the usual sweet spot.
Press Convert to GIF and download the result once sampling finishes.
Why use it
What this tool is good for, and what it deliberately does not try to do.
H.264 in an MP4 container is the one codec combination every browser ships, so MP4 sources decode everywhere — no codec roulette, no refused files.
Seeking is done against the video's own timeline, so the GIF starts exactly where you asked, not at the nearest keyframe guess.
Sampling runs in your tab against a local object URL. There is no upload, no transcoding queue and no email address between you and the file.
