How to use the OGG to MP3 converter
- Add the .ogg or .oga files, or a whole asset folder.
- Choose a bitrate for the MP3; 160–192 kbps matches typical Vorbis music.
- Convert and download.
What is inside an Ogg file
Ogg is only a container. Most files hold Vorbis, newer ones Opus, and a few FLAC. ffmpeg decodes whichever it finds and LAME encodes the MP3, so you never need to check which codec you have.
Vorbis at its common quality 5 setting runs near 160 kbps, which is why a 160–192 kbps MP3 is a fair match. Short mono sound effects convert in a fraction of a second, and longer music tracks take only a few seconds each because audio carries so little data.
Music that loops
Game soundtracks sometimes carry LOOPSTART and LOOPLENGTH comments so the engine can repeat them seamlessly. MP3 players ignore those, so the converted track just plays through once.
MP3 encoding also adds a brief silent lead-in. Music that must loop without any gap is better left as OGG or converted to WAV.
Big asset folders
Game data folders can hold hundreds of small clips. Drop the folder and they are processed one after another, then saved together through the ZIP button.
Silent or damaged files are flagged in the queue without stopping the others, so one bad clip never holds up the batch.
Questions
Why is the MP3 heavier than the OGG?
Vorbis packs sound more efficiently, so the MP3 needs a few more kbps to match it. Pick a lower bitrate when size matters.
What about OGV video?
Video to MP3 handles those. This page expects sound-only Ogg files.
Can I convert Ogg files containing FLAC?
Yes. ffmpeg detects FLAC inside the Ogg container and decodes it before the MP3 is written.
Are Ogg files with Opus audio supported?
Yes. Newer Ogg files often carry Opus, and they convert the same way as Vorbis ones.
