Convert OGG to MP3

This free OGG to MP3 converter changes your Ogg Vorbis (.ogg) file into a MPEG-1 Audio Layer III (.mp3) file, right in your browser. There is nothing to install, no account to create, and no limit on how many files you convert.

100% private. Your file is processed locally in your browser with WebAssembly — it is never uploaded to a server, stored, or seen by anyone.

Share this tool

The conversion runs on your own device using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is never uploaded to a server. MP3 is best for universal music and podcast playback, which is the usual reason to convert from OGG.

Why convert OGG to MP3?

  • MP3 plays on more devices and apps than OGG, so it is the safer choice for sharing.
  • At a sensible bitrate, MP3 stays close in size to OGG while changing the codec.
  • Pick MP3 when you need a file made for universal music and podcast playback.

How to convert OGG to MP3

  1. Add your OGG file

    Drag and drop your .ogg file onto the upload area, or click to browse and pick it from your device.

  2. Start the conversion

    Click "Convert to MP3". Everything runs locally with ffmpeg compiled to WebAssembly (ffmpeg.wasm) - your file stays on your device.

  3. Wait a few seconds

Frequently asked questions

Is this OGG to MP3 converter free?
Yes. It is completely free with no signup, no watermark, and no limit on how many files you convert. It is supported by ads, which keeps the conversion itself free.
Are my files uploaded to a server?
No. The conversion runs locally in your browser using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is processed in memory on your own device and is never uploaded, stored, or seen by anyone.
Will I lose quality converting OGG to MP3?
The audio is re-encoded to MP3, which is lossy. At a sensible bitrate the difference is hard to hear, but converting back and forth repeatedly will degrade quality.
Will the file get smaller or larger?
Roughly the same. OGG and MP3 have comparable size profiles at a sensible bitrate.
What is the difference between OGG and MP3?
OGG is Ogg Vorbis (an Ogg container, typically Vorbis); MP3 is MPEG-1 Audio Layer III (an MP3 container, typically MP3). MP3 is best for universal music and podcast playback, while OGG is best for open-source apps and games.
How long does the conversion take?
Most files finish in a few seconds to under a minute, depending on length and your device. The first conversion is a little slower while the engine downloads and caches, then later runs start instantly.
