About OGG to MP3

OGG Vorbis files from games, Android, or open-source apps are not supported by every player. MP3 is universal.

Vorbis is decoded and re-encoded as MP3. Both are lossy, so use a generous bitrate (192 kbps or higher).

The FFmpeg engine (about 31 MB) downloads the first time you convert and is then cached by your browser. Files up to about 100 MB are supported because everything runs in browser memory.

Frequently Asked Questions

Is OGG to MP3 conversion free?

Yes. No signup, watermark, or daily cap.

Is my file uploaded?

No. FFmpeg runs in this tab as WebAssembly. Only the engine files are downloaded.

Why is it slow on my phone?

Encoding runs on a single CPU thread in the browser. Desktops are much faster; short clips work best on phones.
