Quick answer: To convert AIFF to FLAC, add the AIFF file to the iHateFiles AIFF to FLAC converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. A lossless target, so nothing is thrown away in this step.
Should you convert AIFF to FLAC?
A safe conversion: AIFF and FLAC are both lossless, so the sound is identical and only the file changes.
Every sample survives
AIFF and FLAC are both lossless, so the FLAC decodes to exactly the same samples as the AIFF. Only the packaging changes: about 10 MB per minute as AIFF, 5 to 7 MB as FLAC.
Where the FLAC will play
FLAC plays on VLC, Android, Windows 10 and later, and recent Macs.

What usually goes wrong
About the AIFF. AIFF and WAV are the same audio at the same size; only the byte order and metadata differ. Converting between them changes nothing you can hear.
About the FLAC. Converting an MP3 to FLAC produces a large file that sounds exactly like the MP3. Lossless compression preserves what it is given, including the damage.
How to convert AIFF to FLAC
- Add your AIFF file. It is read from your disk and stays there.

Questions
How do I convert AIFF to FLAC?
Open this page, add your AIFF file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AIFF to FLAC converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to FLAC lose quality?
FLAC is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several AIFF files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
