WEBM is video the way browsers like it: open, royalty-free and built to stream. A Matroska-based container restricted to VP8/VP9/AV1 video with Vorbis or Opus audio.
- Born
- 2010, Google, out of its VP8 acquisition
- Type
- video ยท container
- Typical size
- often smaller than the equivalent MP4: VP9 and AV1 squeeze harder than H.264
- Plays on
- Every modern browser; hit-and-miss in editing apps and on Apple hardware.
- Fun fact
- Google made WEBM royalty-free specifically so the web's <video> tag could work without patent fees.
What this WEBM converter flips
Two directions, one page. Outbound: move WEBM into MP4, WEBM or another container when WEBM proves weak at life outside the browser: editors, TVs and Apple devices get picky: or pull just the audio out as MP3 or WAV. Inbound: re-wrap other footage as WEBM when a tool demands it.
Every WEBM flip
