WebM to GIF —
for screen captures & demos
The format your capture tool produces, converted to the format your README needs. Locally, with hardware acceleration.
Multiple files? Pro converts them all at once.
Converting…
WebM in, GIF out — without a server in between
Developers hit this conversion constantly: capture tools output WebM, but GitHub READMEs, issue trackers and docs want GIFs that just play. GIF Den decodes VP8/VP9/AV1 with your browser's own decoder and encodes the GIF on your machine. Your unreleased feature demo stays yours.
Frequently asked questions
How do I convert a WebM to GIF?
Drop the .webm file on this page, trim the range you want, and convert. VP8, VP9 and AV1 are decoded by your browser in hardware — no upload, no queue.
My screen capture tool outputs WebM. Why?
WebM is the native recording format of browser-based capture tools (Loom-style recorders, browser devtools, OBS browser source). It is efficient for recording, but GIFs auto-play everywhere — including places that block video embeds — which is why converting is so common.
Will quality be lost?
GIF is limited to 256 colors per palette, so gradients and photos lose some fidelity. UI recordings, code demos and animations convert nearly perfectly.
