What is AIFF?

Apple's uncompressed format. Similar to WAV but with better metadata support. Used in professional Mac audio workflows.

What is MP3?

The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.

Why Convert AIFF to MP3?

AIFF files usually mean one thing: music that came out of a Mac. Logic Pro and GarageBand bounce to AIFF by default on many setups, iTunes rips created them for years, and sample libraries ship in AIFF because producers want uncompressed sources. That's exactly right for production — and exactly wrong for sharing. AIFF is uncompressed PCM, so a 4-minute song weighs 40 MB+; email it and it bounces off attachment limits, upload a set of demos and you're moving gigabytes, put a library of them on a phone and the storage vanishes. Converting to MP3 at 320 kbps cuts the size by nearly 80% while staying transparent for normal listening — the person receiving your demo hears the same mix, it just arrives instantly. There's also a plain compatibility angle: while AIFF plays fine on Apple hardware, plenty of Windows apps, Android players, car stereos, and web platforms either refuse .aiff files or handle them clumsily, whereas MP3 plays on absolutely everything. The right workflow is both formats doing their jobs: keep the AIFF (or the project file) as your archival master — MP3 is lossy, and once encoded you can't get the discarded detail back — and generate MP3s as the copies that travel: demos to clients and collaborators, uploads, phone listening, and anywhere size or compatibility matters.

Who Uses This Converter

Send demos & bounces

Logic and GarageBand bounces in AIFF are too big to email. A 320 kbps MP3 sounds the same to the listener and sends instantly.

Portable listening library

Shrink an AIFF collection ~80% so it fits on your phone and plays in every app, on every platform.

Web & platform uploads

Many upload forms reject or mishandle .aiff. MP3 is accepted everywhere your music needs to go.

Sharing outside the Mac world

Windows apps, Android players, and car stereos often stumble on AIFF. MP3 copies play for everyone, no questions.

Frequently Asked Questions

What is AIFF?

Audio Interchange File Format. Apple's version of WAV. It stores uncompressed audio with support for metadata and album art. Common in Mac audio production.

How much smaller will the MP3 be?

About 80% smaller. A 40MB AIFF file becomes roughly 7-8MB as a 320kbps MP3.

Should I use AIFF or WAV for production?

Either works. AIFF has slightly better metadata support on Mac. WAV is more universal. Both are uncompressed with identical audio quality.

Is AIFF the same as Apple Lossless (ALAC)?

No. AIFF is uncompressed (like WAV). ALAC is lossless compressed (like FLAC). ALAC files are smaller but both preserve full quality.

Should I keep the AIFF after converting?

Yes, if it's your own music or an original recording. MP3 is lossy — the discarded detail can't be recovered — so treat the AIFF as the archival master and the MP3 as the copy that travels.

Will my metadata and album art survive?

The audio converts cleanly; basic tags generally carry over, but AIFF and MP3 use different metadata systems, so double-check artwork and tags in your player afterwards and re-tag if needed.

Is this AIFF to MP3 converter free?

Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
