Frequently Asked Questions
Is AIFF or MP3 better quality?
AIFF is lossless and MP3 is lossy. Converting will reduce file size significantly, but some audio detail is permanently removed during compression. Use 320 kbps for the best quality.
Will I lose quality converting AIFF to MP3?
Yes — converting from lossless AIFF to lossy MP3 removes some audio detail. At 320 kbps the difference is inaudible to most people. If you need perfect fidelity, keep the AIFF original.
How long does conversion take?
Seconds for most files. Conversion runs entirely on your device — no upload wait, no server queue. Longer files (over 30 minutes) may take slightly longer.
