Quick answer: To convert FLAC to AIFF, add the FLAC file to the iHateFiles FLAC to AIFF 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 FLAC to AIFF?
A safe conversion: FLAC and AIFF are both lossless, so the sound is identical and only the file changes.
Every sample survives
FLAC and AIFF are both lossless, so the AIFF decodes to exactly the same samples as the FLAC. Only the packaging changes: 5 to 7 MB per minute as FLAC, about 10 MB as AIFF.
Where the AIFF will play
AIFF plays on Macs, Logic, GarageBand and most DAWs.

What usually goes wrong
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.
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.
How to convert FLAC to AIFF
- Add your FLAC file. It is read from your disk and stays there.
- Check the settings. The output format is already set to AIFF.
- Press convert and the AIFF file is saved back to your device.
Questions
How do I convert FLAC to AIFF?
Open this page, add your FLAC 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 FLAC to AIFF 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 AIFF lose quality?
AIFF 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 FLAC files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
