Frequently asked questions
How do I convert AIFF to MP3 on Mac?
Open Picmal, drag your AIFF files into the window, choose MP3 as the output format, set your quality, and click Convert. Everything runs locally on your Mac.
Can I batch convert multiple AIFF files at once?
Yes. Drag in as many AIFF files (or a whole folder) as you like and Picmal converts them all to MP3 in one pass.
Does converting AIFF to MP3 lose quality?
Going from lossless AIFF to MP3 is a lossy step, so some data is discarded. At 256–320 kbps the difference is inaudible to most listeners — pick a high bitrate in Picmal to keep it near-transparent.
