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.
