About OGG and MP3
OGG Vorbis .ogg
An open container, normally holding Vorbis audio. Created specifically to avoid the patent licensing that surrounded MP3.
Good for
- Open and royalty-free
- Better quality than MP3 at the same bitrate
- Standard in games and open-source software
Trade-offs
- Lossy
- Patchy support on consumer hardware
- Largely superseded by Opus for new work
audio/ogg
MP3 .mp3
The format that made digital music portable. Lossy, thirty years old, and still the safest choice when you have no idea what will play the file.
Good for
- Plays on essentially every device ever made
- Small files at listenable quality
- Patents long expired, so support is everywhere
Trade-offs
- Lossy — detail is gone permanently
- Beaten by AAC and Opus at the same bitrate
- No transparency about what was discarded

What changes when you convert OGG to MP3
This is a re-encode, not a repackage
Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.
What your MP3 will contain
The output is MP3 — written by LAME, the reference MP3 encoder, at 192 kbps by default. That sits comfortably above the point most people stop hearing a difference on ordinary equipment, and the bitrate is adjustable from 32 up to 320 if you want the file smaller or the quality nearer the source.
Re-encoding costs a little quality
Both formats are lossy, so this decodes OGG and compresses again as MP3. That second pass loses a small amount on top of what was already gone. It is barely audible once, and it accumulates if a file is converted repeatedly — so convert from the original rather than from a previous conversion.
Tags may not survive intact
OGG stores its metadata as Vorbis comments, and MP3 uses ID3. Standard fields such as title, artist and album normally map across. Anything without an equivalent on the other side — unusual custom fields, some ratings and play counts, occasionally embedded artwork — has nowhere to go. Check the tags before deleting the original if your library depends on them.
