Get a video's soundtrack as an open, royalty-free Ogg Vorbis file for games, Linux players or web projects.

What happens to your MP4

The video track is dropped and the audio is encoded to Vorbis.

Tip: Pick Opus instead for voice: it is more efficient at low bitrates.

How to convert MP4 to OGG

  1. Drop your MP4 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 MP4 (h264 + aac). Paste it into a terminal with FFmpeg installed for batch jobs or files too big for a browser tab:

ffmpeg -y -i input.mp4 -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

Can I keep the original audio untouched?

Choose M4A instead: AAC audio in MP4 is copied without re-encoding.

Is my MP4 file uploaded?

No. The MP4 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 MP4 to OGG?

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