About MP3 to OGG
Ogg Vorbis is the open audio format favoured by game engines such as Godot and Unity, many web apps, Linux software and Wikipedia. It sounds as good as MP3 or better at the same size and has no licensing strings attached. This converter decodes your MP3s and encodes them with libvorbis, the reference Vorbis encoder, compiled to WebAssembly. Choose from four quality levels, from about 112 kbps for small files to about 320 kbps, and convert a whole batch at once.

Does converting lose quality?
