Questions

Which format should I choose?

MP3 plays everywhere; M4A (AAC) sounds better at the same size and suits Apple devices; FLAC and WAV keep every detail, in larger files; OGG (Opus) is small, for the web.

Does converting lose quality?

Converting between lossy formats (MP3, M4A, OGG) loses a little each time; FLAC and WAV keep what the file has.

Why isn't M4A offered?

M4A (AAC) is written by the browser itself: Chrome and Edge on Windows and macOS and Safari can, Firefox and Chrome on Linux can't.
