AIFF (or AIF) is Apple's lossless audio format to store uncompressed PCM audio. It provides CD-quality sound but takes much more disk space than just about all other forms of audio files. If you've got hundreds or thousands of AIFF files, storage and bandwidth will quickly become an issue. What you can do instead of buying more storage space is transform AIFF/AIF into FLAC, a compressed lossless sound format that reduces file size without affecting sound quality.

Here's a top-notch audio converter to help you losslessly convert multiple AIFF files to FLAC at once on Windows. Please read for more details.
