Convert AIFF to iPod Audio — Free Online Converter

AIFF is Apple's native uncompressed format and plays on all iPod models, but at 10 MB per minute it fills even a 160 GB iPod Classic faster than compressed alternatives. The iPod Audio preset encodes AIFF to AAC-LC at parameters that every iPod model — from the 2001 original to the final iPod Touch — handles through its hardware decoder: 44.1 kHz, stereo, 128-256 kbps in M4A.

An iPod Classic with 160 GB can hold about 16,000 minutes of AIFF (266 hours) versus 80,000 minutes of 256 kbps AAC (1,333 hours). That is a 5x difference in library capacity. For iPod Nano (8-16 GB) and Shuffle (2 GB), the difference between AIFF and compressed audio is even more critical. The iPod Audio preset maximizes songs-per-gigabyte while keeping quality excellent.
