# Convert OGG to MP3.

> OGG audio in, universal MP3 out — nothing ever uploaded.

OGG carries Vorbis or Opus audio — efficient, open, and still refused by plenty of players and editors. **Convert it to MP3 without uploading anything**: drop .ogg or .oga files, pick a bitrate, download audio that works everywhere.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## OGG, OGA, OPUS — which page?

They are siblings: .ogg and .oga are the same Ogg container, and .opus is Ogg carrying Opus under its own extension — voice messages usually arrive that way, and [OPUS to MP3](https://compress-pro.com/opus-to-mp3) handles them. All of them convert here too; for bitrate advice and target-size mode, see the [audio tool](https://compress-pro.com/compress-audio).

## Frequently asked questions

### What is inside an OGG file?

Usually Vorbis or Opus audio — game soundtracks, podcast feeds and open-source rips ship this way. Both decode here in the browser and re-encode straight to MP3.

### What about .oga files?

Same container, different label — .oga is the “audio-only Ogg” extension. Drop them exactly like .ogg files; the conversion is identical.

### Does quality survive the conversion?

Both directions are lossy, so match or exceed the source: 192 kbps MP3 for music keeps the difference inaudible, 128 kbps is plenty for speech. Batches convert in one go and download as a ZIP.

### Is it private?

Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
