About WEBM and OGG

WebM .webm

An open container built for the web, holding VP8, VP9 or AV1 video with Vorbis or Opus audio. Royalty-free by design.

Good for

  • Open and royalty-free
  • Smaller than H.264 MP4 at similar quality
  • Supports transparency, which MP4 does not

Trade-offs

  • Weaker support in desktop editors and older devices
  • Slower to encode than H.264
  • Not the safe choice for sending a file to someone

video/webm

OGG Vorbis .ogg

An open container, normally holding Vorbis audio. Created specifically to avoid the patent licensing that surrounded MP3.

Good for

  • Open and royalty-free
  • Better quality than MP3 at the same bitrate
  • Standard in games and open-source software

Trade-offs

  • Lossy
  • Patchy support on consumer hardware
  • Largely superseded by Opus for new work

What changes when you convert WEBM to OGG

Only the sound is kept

This takes the audio track out of the WEBM and writes it as OGG. The picture is discarded entirely, and no conversion back will return it — keep the WEBM if you still need the video.

This is a re-encode, not a repackage

Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.

What your OGG will contain

The output is Vorbis — at 192 kbps by default. Vorbis is royalty-free and holds up slightly better than MP3 at the same bitrate, though Opus has largely superseded it for anything new — choose OGG when something specifically expects it.
