MP4 is the most common video format on the web. Turn any MP4 clip into a looping GIF you can drop into chat, a README or a bug report — all on your device.
A GIF made from an MP4 loops automatically and plays inline everywhere — Slack, Discord, GitHub, docs — without a player or a click. That makes short MP4 demos and reactions far more useful as GIFs.
Unlike converters that ask you to upload your MP4 and wait, SimpleGIF keeps everything local. The whole conversion runs on your own machine with WebAssembly — the file is never uploaded to a server, so nothing leaves this browser tab. No queue, no upload limit, no account.
Dial in exactly the GIF you want: trim to the moment that matters, lower the FPS to shrink the file, cap the width, speed it up or slow it down, and toggle infinite looping. Preview the result and re-render instantly until it is right.
Your MP4 is processed by ffmpeg compiled to WebAssembly, right in this tab. No server ever sees it.
Trim, FPS, output width, playback speed and looping — the knobs that decide how the GIF looks and weighs.
Tweak a setting and convert again without re-loading the file. A live progress bar tracks every frame.
Drag your MP4 into the converter, trim the section you want, set the frame rate and width, then convert and download the looping GIF.
Yes — completely free, no watermark, no sign-up, and no limit on how many files you convert.
No. Conversion happens in your browser with WebAssembly, so your MP4 stays entirely on your device.
Lower the FPS, reduce the output width, and trim the clip shorter. Each of these shrinks the GIF, and you can preview the size before downloading.
