About AIFF to MP3

Convert uncompressed AIFF files — Apple's PCM format — into MP3 that plays on virtually any device while taking up a fraction of the space. Choose a bitrate and we transcode to MP3 with the LAME (libmp3lame) encoder locally.

The conversion runs entirely in your browser via WebAssembly. Your AIFF never leaves your device and nothing is uploaded.
