Frequently asked questions
Does converting MP3 to FLAC improve quality?
No. Converting a lossy file to a lossless format keeps the existing quality but cannot restore what was lost.
Which format has the best quality?
FLAC and WAV are lossless. FLAC is compressed and much smaller than WAV.
Can I convert several files at once?
Yes, up to 5 files per job with the same settings.
