About video to GIF

MP4 is the video format almost every phone, camera and app produces — and the one GIFs are most often cut from. GIF is a 256-color image format that autoplays anywhere: chats, docs, issue trackers, places video can't go.

OptImg plays your MP4 with the browser's own player and rebuilds the frames as a GIF on your device: nothing is uploaded, no queue, no watermark. Up to 15 seconds per GIF; the start point, frame rate and width are yours to tune.

Frequently asked questions

Is my MP4 uploaded to a server?
No. The MP4 is played and converted entirely in your browser: it never leaves your device, and there's no queue and no watermark.
How long can the GIF be?
Up to 15 seconds per GIF (at most 200 frames). Long GIFs get huge fast — short clips at 10 fps are what the format does best.
Why is the GIF bigger than my video?
GIF is a 1987-era format: 256 colors per frame and no motion compression, so it can't match modern video codecs. Keep clips short and pick 10 fps and a smaller width for shareable sizes.
