How to convert WebM to GIF
- Add your files. Drop WebM files anywhere on the page, or use Choose files. Folders and ZIP archives work too; every WebM inside is picked up.
- Check that GIF is selected. GIF is already chosen on this page. Other formats in the same row are one tap away if you change your mind.
- Adjust options if you need to. Choose the frame rate, width and how many seconds to include.
- Convert and download. Press Convert. Each file shows its progress, then a Download button. With several files, “Download all” gives you a single ZIP.
What happens to your WebM
A GIF has no sound and only 256 colours per frame, so Myriadfile samples frames from your WebM at the rate you pick (8, 10 or 15 frames a second), scales them to the width you choose, builds an optimised palette for every frame and writes them into one looping GIF.
GIF files grow quickly with length, size and frame rate, which is why the length option starts at the first 5, 10, 15 or 30 seconds. For trimming, cropping and speed control, use the dedicated video to GIF tool.
About WebM and GIF
WebM: WebM is an open web video format using VP8, VP9 or AV1 video with Opus or Vorbis audio. Browsers play it natively; Apple devices and editors are less reliable.
GIF: GIF is an old format limited to 256 colours that supports simple animation and transparency. It is still used for short loops and simple graphics.
Questions
Is my WebM file uploaded anywhere?
No. The conversion runs inside this browser tab using code served by this site, and the GIF is created on your device. You can even disconnect from the internet once the page and its converter have loaded.
Why is my GIF so large?
GIF compresses poorly compared with video. A smaller width, a lower frame rate or a shorter length makes the file much smaller. For long clips, an MP4 or WebM is usually the better choice.
Can I convert several WebM files at once?
Yes. Drop as many WebM files as you like, a whole folder or a ZIP. They convert one after another, and “Download all” saves every GIF in one ZIP that keeps your folder structure.
Is there a file size limit?
There is no fixed limit, because nothing is uploaded. The practical limit is your device’s memory: a phone may struggle with very large videos that a laptop converts easily.
