How to convert FLAC to AIFF

  1. Add your .FLAC file - drop it in the box above or click to browse.
  2. Convert it to .AIFF in a few seconds.
  3. Download your new .AIFF file.

What to expect

  • AIFF is uncompressed: a FLAC file at 150 MB typically expands to around 300 MB as AIFF, so keep the FLAC as your archive master.
  • Tags may not transfer cleanly - FLAC uses Vorbis Comments while AIFF uses a different metadata format; check titles, artist fields, and cover art after converting.
  • Some apps only accept .aif while others expect .aiff; both extensions refer to the same format, so rename if an app rejects the file.

Frequently asked questions

Does converting FLAC to AIFF lose audio quality?
No - both formats are lossless, so the decoded audio written into the AIFF container is bit-perfect.
Why is the AIFF file so much bigger than the FLAC?
FLAC compresses audio losslessly to roughly 50-70% of raw PCM size; AIFF stores audio uncompressed, so the file roughly doubles.
Will a hi-res 24-bit / 96 kHz FLAC stay hi-res after conversion?
Yes - tools like ffmpeg and XLD carry the bit depth and sample rate through unchanged.
Should I keep the original FLAC after converting?
Yes; FLAC is smaller, equally lossless, and widely supported - convert to AIFF only for the app that needs it.
