ConvertWhat happens when you convert GIF to WebM
- Every frame of the GIF is kept with its original timing. Transparent areas become white, because WebM video has no transparency.
- WebM is usually 5–10× smaller than the GIF and can be posted where GIFs aren't allowed.
- Everything runs on your device. Very long or 4K videos need a lot of memory; on phones, keep videos under about 1 GB.

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many GIF files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting GIF to WebM reduce quality?
The video looks the same as the GIF. It can even look better, because video isn't limited to 256 colors.
Is there a file size limit?
Nothing is uploaded, so there's no upload limit. The limit is your device's memory: a few GB is fine on most computers; on phones, stay under about 1 GB.
How long does it take?
Copying a stream takes seconds. Re-encoding uses your device's hardware encoder and is usually faster than real time on a computer.
Will the video have sound?
No. GIFs have no audio, so the video is silent.
