How to convert AIF to FLAC

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

What to expect

  • The conversion is lossless: .flac stores the exact same audio data as .aif, so nothing is degraded and you can convert back to .aif for bit-identical PCM.
  • File size typically drops to around 50% of the original .aif, though dense or noisy recordings compress less than quiet or sparse ones.
  • FLAC compression level (0-8) only affects file size and encoding speed, not sound quality; the default level 5 is a good balance.

Frequently asked questions

Does converting AIF to FLAC lose quality?
No - both are lossless formats, so the audio is bit-perfect after conversion and nothing is degraded.
How much smaller will the FLAC file be?
Usually around half the size of the original .aif, though the exact ratio depends on the audio content.
Can I convert back to AIF after converting to FLAC?
Yes, because FLAC is lossless you can export back to .aif and get the same PCM audio you started with.
Are .aif and .aiff the same format?
Yes - .aif and .aiff are both Apple Interchange File Format and convert to FLAC identically.
