About MP3 to OGG

Game engines and some open-source apps prefer OGG Vorbis. Convert MP3 sound effects or music for them.

Encoded with Vorbis at quality 5 (around 160 kbps). Converting lossy to lossy loses a little more detail.

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.
