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.
Expect roughly 20× smaller: AIFF runs about 10 MB per minute, Opus about 0.5. Because AIFF is uncompressed, this is the ideal encode: the encoder sees the complete original signal, so the Opus is the cleanest that audio can produce.
Most people meet AIFF through Logic Pro and GarageBand bounces. It is a fine format there; the trouble is that AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. Opus is the destination because it plays essentially everywhere — Discord recordings and every ordinary phone, browser, and player. AIFF costs you around 10 MB for every minute; Opus asks for about 0.5. Over a long recording that gap is the whole reason to convert. Because AIFF is uncompressed, encoding to Opus here is the clean, single-generation case — the encoder sees the whole original signal, so this Opus is as good as the format gets.
Frequently Asked Questions
Do I need an account to convert AIFF to Opus?
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?
Because AIFF is uncompressed, this is the ideal encode: the encoder sees the complete original signal, so the Opus is the cleanest that audio can produce.
