What is a WebM file?
WebM, an open video format from Google

FAQ
Questions, answered
Is the 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. Everything 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.
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 I convert WebM to?
MP4, MOV, MKV, MP3, WAV, M4A, OGG, FLAC, AAC, GIF, AVI, WMV, and MPEG. Pick the format after adding your file.
