About MP3 and 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
audio/mpeg
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- Largely superseded by Opus for new work

What changes when you convert MP3 to OGG
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 OGG will contain
The output is Vorbis — at 192 kbps by default. Vorbis is royalty-free and holds up slightly better than MP3 at the same bitrate, though Opus has largely superseded it for anything new — choose OGG when something specifically expects it.
Re-encoding costs a little quality
Both formats are lossy, so this decodes MP3 and compresses again as OGG. 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
MP3 stores its metadata as ID3, and OGG uses Vorbis comments. 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.
