AIFF (.aiff) · Max 20 MB
Most converter sites force you to create an account before converting. It's a growth hack, not a feature. AudioUtils skips all that. The converter works immediately.
Free users get 5 conversions per month without any account. Need more? Pro accounts exist but are never required for basic use.
No signup also means no tracking profile tied to your conversions, no email list, and no database of your files to breach — because there is no database. The conversion happens in your browser and the AIFF never leaves your device.
Sizes are comparable: AIFF and FLAC both sit near 10–5 MB per stereo minute, so this conversion is about compatibility, not storage. Nothing is discarded. AIFF and FLAC both preserve the audio exactly; you're changing the container, not the content.
AIFF files come from Logic Pro and GarageBand bounces, old iTunes rips, and Mac sample libraries. AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email — which is the whole reason this conversion exists. FLAC is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. File size stays in the same ballpark — both formats land around 10–5 MB per minute. Both AIFF and FLAC are lossless, so this specific conversion is bit-perfect: every sample survives and you can go back to AIFF later without any loss.
Frequently Asked Questions
Do I need an account to convert AIFF to FLAC?
No. No signup, no email, no verification link, and no "confirm your inbox" step. The converter works the second the page loads and the download isn't gated.
Why do other converters demand an email address?
Because the address is the product. Nothing about converting audio technically requires an account — the requirement is a growth tactic, and this converter is the proof.
Is there a hidden limit without an account?
Nothing hidden: 5 conversions per month with files up to 20MB file size limit and a 10-second preview output. Pro exists but is never required.
Without an account, where is my file stored?
Nowhere. There's no account because there's no server-side storage — the AIFF is converted in your browser and never uploaded.
What does the conversion do to the audio?
Nothing is discarded. AIFF and FLAC both preserve the audio exactly; you're changing the container, not the content.
