FLAC is the archivist favourite: it compresses audio without losing a single sample, so a FLAC library is a faithful copy of the original recording. The catch is that Apple devices and editors have never embraced FLAC the way they embrace AIFF. This free flac to aiff converter decodes a FLAC track and rewrites it as an AIFF that Apple workflows accept without a second thought. Everything runs in your browser, so your file is never uploaded and no signup is needed. The honest limit: the AIFF output is 16-bit PCM, so a 24-bit FLAC is requantised to 16-bit in the move. A standard 16-bit FLAC carries over with its samples intact.

How to use this flac to aiff converter

From a lossless archive file to an Apple-friendly AIFF.

1Drop in your FLAC

Choose a .flac file from your music archive or a lossless download.

2Convert in your browser

Lossless decoding and AIFF writing happen on your own device, so nothing is uploaded.

3Download the AIFF

Save the file for an Apple device, a Mac editor or a media library that prefers AIFF.

Why this flac to aiff converter is the archive-to-Apple bridge

Keep the archive in FLAC. Use AIFF where Apple expects it.

Lossless source, editable result

FLAC decoding loses nothing, so the AIFF starts from the full recording rather than from a compressed copy.

Apple workflows without friction

AIFF plays and edits natively across macOS tools, where FLAC support has always been patchy.

Original left untouched

Conversion creates a new file. Your FLAC archive stays exactly as it was.

Private by design

A personal music collection is converted on your own device and never uploaded.

FLAC to AIFF Converter FAQs

Short, direct answers to the questions readers ask most.

Yes. Its source is lossless, so unlike MP3 or OGG conversion, nothing was discarded before the conversion started. The only limit is the 16-bit output.

Yes. FLAC compresses losslessly, while AIFF stores every sample uncompressed, so the AIFF takes more space.
