MP3 to OGG converter

Game engines (Unity, Godot), some Linux apps and web audio projects prefer Ogg Vorbis.

What happens to your MP3

MP3 audio is decoded and encoded to Vorbis (quality 5, about 160 kbps) in an Ogg file.

Tip: Converting lossy to lossy loses a little each time. If you have the original WAV or FLAC, convert from that.

How to convert MP3 to OGG

  1. Drop your MP3 file on the box above, or tap it to pick one. The engine (about 31 MB) loads once per visit.
  2. The converter reads the file's streams and shows which codecs are inside.
  3. Pick a bitrate, or leave the default to keep the original audio when possible.
  4. Press the button, wait for the progress bar, then download your OGG.

Prefer the command line?

This is the FFmpeg command the converter runs for a typical MP3 (mp3). Paste it into a terminal with FFmpeg installed for batch jobs or files too big for a browser tab:

ffmpeg -y -i input.mp3 -vn -sn -c:a libvorbis -q:a 5 output.ogg

This re-encodes, so expect it to take a while on long files. Your own file may contain different codecs; the converter above detects them and adapts. For other jobs, ask the FFmpeg command helper.

Questions

Is OGG better than MP3?

At the same bitrate Vorbis usually sounds slightly better, and it is patent-free. MP3 is more compatible.

Is my MP3 file uploaded?

No. The MP3 is read from your device by FFmpeg running as WebAssembly in the page, and the OGG is written back to your device. No server ever receives it.

Is there a size limit for MP3 to OGG?

We set none. The practical limit is browser memory: roughly 2 GB of output on a computer, and much less on phones.
