Frequently Asked Questions
How do I convert AIFF to MP3 for free?

What is an AIFF file?
AIFF (Audio Interchange File Format) is Apple's uncompressed, lossless audio format, developed in the 1980s and widely used on macOS. It stores audio bit-for-bit like WAV does, which makes AIFF files large but high quality. Logic Pro, GarageBand, and Pro Tools all export AIFF by default.
Why convert AIFF to MP3?
AIFF is uncompressed, so files are roughly 10 times larger than an MP3 of the same song. Converting to 192 kbps MP3 shrinks a 40 MB AIFF down to about 4 MB — easy to share, upload, or load onto a phone. MP3 is also playable on every device, while non-Mac systems sometimes struggle with AIFF.
Does quality drop when I convert AIFF to MP3?
Yes, this is a lossless-to-lossy conversion, so some audio data is discarded. At 192 kbps most listeners cannot hear the difference on phones, laptops, or car stereos, but it is not bit-perfect. Keep your AIFF masters for archival or mastering work and use the MP3 copies for sharing and daily listening.
Can I convert AIFF exported from Logic Pro or GarageBand?
Yes. AIFF files exported from Logic Pro, GarageBand, Pro Tools, macOS voice memos, or any other Mac app all work the same way. Drop the file into the converter and download the MP3 — the original AIFF on your Mac is untouched.
Does my browser support AIFF decoding?
Chrome and Firefox on desktop and mobile can decode AIFF natively through the Web Audio API. Older versions of Safari have limited AIFF support. If the converter shows a decode error, open the page in Chrome or Firefox and try again.
Is my AIFF file uploaded to a server?
No. The converter runs entirely in your browser using the Web Audio API. Your AIFF file never leaves your device — nothing is uploaded, stored, or analyzed.
Is it free?
Yes. Completely free. No sign-up, no watermark, no ads, no conversion limits. Max file size is 200 MB per file.
