Frequently asked questions
Should I convert to MP3, WAV, or FLAC?
Use MP3 (or AAC) for sharing and everyday listening — small files that play everywhere. Use WAV for recording and editing, and FLAC to archive music losslessly at ~half the size of WAV.
Does converting audio to MP3 reduce quality?
MP3 is lossy, so some data is discarded — but at 256–320 kbps the difference is inaudible to most listeners. Converting from a lossless source like WAV or FLAC gives the best MP3 quality.
What's the difference between lossy and lossless audio?
Lossless formats (WAV, FLAC) preserve every sample exactly. Lossy formats (MP3, AAC, OGG) discard inaudible detail to shrink files — perfect for streaming, podcasts and portable players.
