About this tool
OGG Vorbis is what game engines (Unity, Godot, Source, RPG Maker), Discord soundboards, and many open-source apps expect for music and sound effects. Converting MP3 to OGG in your browser gives you a file at the quality level you choose; at q6 (about 192 kbps) the result is indistinguishable from the source, and Vorbis loops cleanly where MP3 leaves an audible gap.
About the formats: MP3 is the universal lossy audio format. Practically every device, car stereo, and app made in the last 25 years plays it, and at 192-320 kbps it is indistinguishable from the original for most listeners. OGG files hold Vorbis or Opus audio, open formats used by games, Linux software, and some voice recorders. Quality per megabyte is excellent, but device support outside the desktop is spotty.

Questions
Does MP3 to OGG lose quality?
Both formats are lossy, so re-encoding loses a little. Keep the quality at q6 or higher and you will not hear the difference.
Why do games prefer OGG?
Vorbis has no encoder padding, so looping music restarts seamlessly, and the format is royalty-free, which is why most engines ship a Vorbis decoder and not an MP3 one.
Is this Opus or Vorbis?
Vorbis, the widely supported codec that every engine and player understands.
Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
