About WebM to GIF
Browser and screen recordings saved as WebM can become GIFs for GitHub issues, Slack, or documentation that does not embed video.
Set start, length, width, and frame rate. Shorter clips at 8–12 fps and 480 px wide stay manageable.
The FFmpeg engine (about 31 MB) downloads the first time you convert and is then cached by your browser. Files up to about 100 MB are supported because everything runs in browser memory.
