What is inside a WEBM file?

WEBM is a container developed for the web. Its audio is almost always Opus (modern, very efficient, used for voice and video calls) or Vorbis (older). Both sound good, but support outside web browsers is limited. MP3 is decades older and less efficient, yet it is the one audio format that every device understands.

Frequently asked questions

Can I convert an audio-only WEBM recording?

What quality is best for voice recordings?

128 kbps is plenty for speech and keeps the file small.

Why use MP3 instead of WEBM?

Many phones, car stereos and older programs cannot play WEBM. MP3 works everywhere.
