About this tool

Convert Ogg Vorbis and Opus to MP3

This tool converts OGG files to MP3 right in your browser. It reads both kinds of Ogg, Vorbis music and Opus voice messages, and makes an MP3 of 128, 192 or 320 kbps that plays on any phone, car stereo or player. Your files never leave your device.

Vorbis and Opus: both kinds of Ogg

Ogg is a wrapper, and two sound formats live in it. Vorbis is the older: game soundtracks, sound effect packs, music from open-source projects and recordings from Audacity. Opus is the newer, made for speech: voice messages that chat apps save, and recordings from calls.

Both are read here. Opus always runs at 48 kHz, which MP3 has, so a voice message comes out at its own rate; a Vorbis file at 44.1 or 48 kHz does too. A voice message is usually mono, so its MP3 is mono, at half the bitrate you pick.

An MP3 plays where an Ogg doesn’t

Plenty of players and car stereos have never learned to open Ogg, and a form on a website or an editor may ask for MP3 only. The MP3 is the format everything takes.

Ogg and MP3 are both compressed, so the MP3 is a second lossy copy and can’t be better than the Ogg. For music take High (192 kbps) or Best (320 kbps); for a voice message Standard (128 kbps) is plenty.

Fast, and your files stay put

A 4-minute Ogg of 3.8 MB became an MP3 in about 3 seconds on a recent laptop.

The browser’s own decoder reads the Ogg and ToolHero’s MP3 encoder writes the new file; nothing is sent to a server. Ogg files carry their tags as Vorbis comments, and the title, artist and album come along into the MP3 where there are some.

Older browsers

Chrome, Edge and Firefox decode both kinds of Ogg themselves. Safari before version 26 asks the page’s own decoder for it, which holds the whole decoded sound in memory, so it works for up to 10 minutes of sound there; a longer file says so. If a browser can’t decode an Ogg at all, the row says that instead of making an empty MP3.

How it works

  1. Add your OGG files

    Drop Vorbis music or Opus voice messages here, or choose them.

  2. Choose a quality

    High (192 kbps) is the default; voice messages get half of it, as they are mono.

  3. Convert and save

    Press Convert, then save the MP3, or several as a .zip.

Questions, answered

Does it open Opus voice messages as well as Vorbis music?

Yes. Both live in Ogg files, and both are read. A voice message in Opus becomes a mono MP3 at half the bitrate you pick.

What is the difference between OGG and OPUS files?

Opus files are usually Ogg files too, holding Opus sound; the extension is just a hint. This tool reads the sound, not the name, so either works.

Will it keep the track’s title and artist?

Yes, where the Ogg has them. They come along into the MP3, except in Safari before version 26, where the file is decoded by the browser itself.

Why did my OGG file not convert?

The row says why. It may be damaged or cut short, the browser may be unable to decode it, or in Safari before version 26 it may be longer than the 10 minutes the browser’s decoder can take at a time.
