What is an AIFC file?
AIFC (AIFF-C) is the extended AIFF format that allows compression and little-endian audio. Modern macOS often writes uncompressed little-endian ("sowt") audio as AIFC.
AIFC is mainly used for macOS system sounds and some audio exports. It plays on Macs, QuickTime and most audio editors.

Frequently asked questions
How do I open an AIFC file?
AIFC files play on Macs, QuickTime and most audio editors. If yours will not open, convert it to MP3 on this page; that format plays on any device.
How do I convert a file to AIFC?
Drop any audio file on this page. "Convert to" is set to AIFC automatically for files that are not AIFC already.
Do I have to pay or sign up to use the AIFC converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Is AIFC lossless?
It depends on the codec inside: AIFC can hold both compressed and uncompressed data.
