Best practices for AIFF
Small choices that keep your output sounding right.
- Play the first converted file before batch-converting the rest, so you catch a wrong setting early.
- AIFF is lossless — ideal for editing or archiving. Expect files several times larger than an MP3 or AAC equivalent.
- Check that title, artist, album and cover art survived the conversion; some players cache old tags.
