The formats
GIF and WebM at a glance
What is a GIF file?
GIF is a decades-old image format best known for short looping animations. Each frame can use at most 256 colors, which suits simple graphics but makes photos look grainy, and it supports only on-or-off transparency. GIFs have no sound. It opens in every browser, messaging app, and social network, plus Windows Photos, macOS Preview, and image editors.
What is a WebM file?
WebM is an open, royalty-free video format from Google, built for the web. It holds VP8, VP9, or AV1 video with Opus or Vorbis audio, and it's what Chrome and many screen recorders, including Ethical Tube, save by default. QuickTime, iMovie, and some editors can't open it. It opens in Chrome, Edge, Firefox, and Safari, VLC, YouTube, Google Drive, and editors like Shotcut and Kdenlive. QuickTime and iMovie can't open it.
Good to know
What changes when you convert GIF to WebM
- Every frame keeps its timing, and the WebM is usually a fraction of the GIF's size.
- WebM doesn't support transparency, so transparent areas become black.
- The video has no sound, since GIFs don't have any.
- Copy-protected (DRM) files can't be converted.
- Very long videos can run out of memory, especially on phones.
FAQ
Questions, answered
Is this GIF to WebM converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with Mediabunny and your browser's WebCodecs video encoders, so your files never leave your device. Once the page has loaded, it even works offline.
Can I convert several GIF files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each WebM file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in current versions of Chrome, Edge, Safari, and Firefox. Phones handle short clips well, and long or 4K videos convert best on a computer.
What can open a WebM file?
Chrome, Edge, Firefox, and Safari, VLC, YouTube, Google Drive, and editors like Shotcut and Kdenlive. QuickTime and iMovie can't open it.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle images up to about 100 megapixels.
