Right for speech, wrong for music. At a fixed quality the file size does not change — but mono tolerates a much lower quality than stereo, so combine the two to actually shrink the file.

Leave at 0 for the whole file.

0 means run to the end.

  • No upload The conversion runs in this tab. Your file never travels — not to us, and not to the advertising.
  • No sign-up, no email, no daily cap There is no account system to sign up to.
  • No size limit we invented Only your device's memory — about ~2 GB on a desktop browser, ~400 MB on a phone.
  • Turn your Wi-Fi off and convert anyway The conversion needs nothing but this page. Ads will not load without a connection; your file will still convert. That is the whole claim, and it takes five seconds to check.

Compresses WAV into an Ogg file using Opus. Worth choosing over MP3 when the target is a game engine, a web page or a Linux application — Opus is both smaller and better at the same bitrate.

Opus rather than Vorbis

Ogg can hold either. This writes Opus, which supersedes Vorbis on every measure: better quality at every bitrate, lower latency, and better handling of both speech and music.

The only reason to prefer Vorbis today is a piece of software that predates Opus and never added support — some older game engines are in that position. If you need Vorbis specifically, a desktop encoder is the route.

Where Opus is the right choice

Web audio, game audio, voice chat, and anywhere the patent position of MP3 and AAC is a concern. Every browser supports it. Consumer hardware largely does not, which is the trade-off.

Bitrates that actually make sense for Opus

Opus is efficient enough that the numbers people remember from MP3 are misleading. Stereo music is hard to distinguish from the source at 96 kbit/s and genuinely transparent for most listeners by 128. Mono speech is clear at 24 and perfectly usable at 16, which is roughly a tenth of what the same recording would need as an MP3. Setting 320 out of habit produces a file several times larger with nothing to show for it — the encoder is not holding anything back at 128.

Questions

Vorbis or Opus?
Opus, which this produces. It beats Vorbis at every bitrate. Only very old game engines still need Vorbis specifically.
Is it better than MP3?
Yes, at equal bitrate, by a comfortable margin. It is also far less widely supported by hardware.
Is my file uploaded?
No. The demuxing, decoding and encoding all happen in this tab using the browser’s own media stack plus a WebAssembly encoder. A recording can be an interview, a lecture, a private call — none of it is transmitted. Turn your Wi-Fi off after the page loads and it still works.
How large a file can I convert?
There is no imposed limit, only your device’s memory — around 2 GB in a desktop browser and 400 MB on a phone, since the file is held in memory while it converts. A two-hour video converts in well under a minute on a laptop.
