AIFF to FLAC Converter

Convert AIFF files to FLAC. Free, without uploading.

This tool converts AIFF files to FLAC. AIFF is Apple’s uncompressed audio format, the Mac counterpart of WAV.

FLAC is lossless compressed audio: about half the size of WAV with no quality loss. FLAC is lossless, so the audio keeps the quality it has in the AIFF file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the AIFF file, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the FLAC file.

Frequently asked questions

Will audio quality drop when converting to FLAC?

Is there a file size limit?

No fixed limit; your device’s memory decides. Computers usually handle files up to 1–2 GB.

Is my file uploaded?

No. Your AIFF file is converted to FLAC inside your browser.
