How to convert MP3 to Ogg

Open an MP3, or a folder of them, and save each one as Ogg for a game engine, a web page, or an app that wants an open format. The MP3 to Ogg converter runs in your browser, so nothing is uploaded.

  1. Step 1

    Choose your MP3 files
    Pick one or many, or drop them into the converter above.

  2. Step 2

    Keep Ogg
    Ogg is selected; choose another audio format if you need one.

  3. Step 3

    Download the Ogg
    Save each file when it's converted.

What to expect

Supported inputs
MP3 files and any other audio or video file.
What happens
The sound is re-encoded as Opus in an Ogg file. Ogg is selected first; you can choose another audio format.
Limits
Opus works at 48 kHz, so other rates are resampled. Very long recordings depend on your device's memory.

Questions

Opus, which sounds better than Vorbis at the same size. Unity, Godot, and every current browser play it.

No. The sound is encoded again, so detail the MP3 left out doesn't come back. Convert when a game or an app needs Ogg.
