Convert AIFF to FLAC
Compress AIFF masters to FLAC — substantially smaller, bit-perfect, and far better supported outside the Mac.
This conversion runs in this browser tab. The selected file is not uploaded for processing.
AIFF to FLAC, step by step.
These steps describe the AIFF input and the FLAC export for this exact route.
Upload AIFF Files
Drag and drop your AIFF files or click to browse. You can queue several at once.
Convert in Your Browser
The first run fetches the conversion engine (a one-time ~31MB download); after that, AIFF to FLAC conversion happens entirely on your device — nothing is uploaded.
Download FLAC
Save the converted file right away. Multiple files are bundled into a ZIP for one-click download.
What to expect
What matters for FLAC output.
Review the behavior this AIFF to FLAC tool is designed to preserve, expose, or simplify.
100% Private
All processing happens in your browser. Your files never leave your device.
Lossless Compression
FLAC shrinks audio to roughly half of WAV size while staying bit-perfect — decode it and you get the original samples back exactly.
One-Time Engine Download
The first conversion fetches a ~31MB audio engine; your browser caches it, and everything runs locally from then on.
Questions about AIFF and FLAC.
Check the format behavior, limitations, and follow-up options before processing a real file.
An AIFF archive eats disk at about 10MB per minute, and FLAC stores the same audio bit-for-bit at roughly half that. For archiving session bounces, CD rips, and finished masters, FLAC is the standard answer: lossless, taggable, and playable across platforms that never learned AIFF. Decode the FLAC later and you get your exact original samples back.
