2. Choose MP3 and a bitrate
MP3 is already selected. Pick a bitrate — 320 kbps for best quality, 192 or 128 kbps for smaller files.
3. Convert & download
Click Convert & Download. Your MP3 downloads automatically, ready to play anywhere.
M4A and MP3 Are Both Lossy
M4A files hold AAC audio, which — like MP3 — is lossy. Converting M4A to MP3 re-encodes already-compressed audio, so it preserves quality rather than improving it; a high bitrate (320 kbps) keeps the result transparent. MP3's advantage here is universality: it plays on hardware that won't read M4A. To compare the formats, see MP3 vs M4A. Need the reverse? Use MP3 to M4A.
