MP4 to GIF Converter

Turn an MP4 clip into a high-quality animated GIF entirely in your browser. A two-pass color palette keeps the result sharp, and nothing is ever uploaded — the conversion runs on your own device.

Converting MP4 to GIF the right way

MP4 uses millions of colors; GIF supports only 256. A naive conversion produces banding and dithering noise. This tool runs a two-pass palette: first it analyzes your clip to build the optimal 256-color palette, then renders the GIF against it — the same technique used by professional FFmpeg workflows, so your GIF stays crisp.

Frequently asked questions

Why is my GIF bigger than the MP4?
GIF is an old, inefficient format with no modern video compression, so a few seconds of motion can exceed the source MP4. Keep GIFs short, lower the width, or reduce the frame rate to shrink the file.
How do I keep the GIF file small?
Trim to the few seconds you need, drop the width to 320–480px, and use 10–15 fps. Those three levers control GIF size far more than anything else.
