About converting MP3 to AIFF
MP3 and AIFF solve different problems, which is why this conversion is so common. Our converter reads the structure of your MP3 file and rebuilds it as a valid AIFF file rather than simply renaming it, so the result opens cleanly in the apps you already use.
MP3 is the most widely supported compressed audio format. AIFF is Apple's uncompressed audio format.
The converter sits in our audio converters toolkit alongside MP3, WAV, FLAC, M4A, AAC, OGG, WMA, AIFF, AMR and more. Nothing is installed, nothing is stored, and the output carries no watermark.
