AIFF converter

AIFF converts to MP3 right in your browser, so your recording stays on your device. WebAssembly does the encoding, free and unlimited.

What is AIFF?

AIFF is Apple's uncompressed audio format, the Mac counterpart to WAV: studio-quality, lossless, and large, common in GarageBand and Logic exports. The full fidelity is overkill for sharing, where an MP3 is a fraction of the size. Converting keeps the sound and drops the bulk.

Common questions about AIFF

What is an AIFF file?
AIFF (Audio Interchange File Format) is Apple's uncompressed, lossless audio format, the Mac counterpart to WAV. It stores raw PCM audio at full studio quality, which is why GarageBand, Logic, and other Mac tools often export to it. The tradeoff is size: an AIFF is large, roughly ten times bigger than an MP3 of the same recording, which is overkill for sharing or carrying around.
How do I convert AIFF to MP3?
Drop your .aiff file into hushvert and choose MP3. The encode runs in your browser through WebAssembly, so your recording never uploads anywhere. It is free and unlimited with no account. hushvert converts AIFF out to MP3; it does not create AIFF, since AIFF is a source format rather than a sharing target.
Is converting AIFF to MP3 private? Does my recording get uploaded?
No upload. AIFF to MP3 is client-side, so the file is decoded and encoded entirely on your device. You can confirm it in airplane mode or by watching the Network tab while it runs, and there is a live demonstration on our /privacy-proof page. That matters for unreleased music or original recordings you do not want sent to a server.
Will I lose quality converting AIFF to MP3?
Some, by design. AIFF is lossless, so going to MP3 is the first lossy step and it does discard some data to shrink the file. hushvert encodes at a high bitrate, where the difference is hard to hear on most material, but it is a real change. If you need to preserve the full master, keep the AIFF and treat the MP3 as your shareable copy rather than the archive.
Why convert AIFF to MP3 instead of keeping the lossless file?
Size and reach. An AIFF holds full uncompressed audio, which is exactly what you want for editing and archiving but impractical for emailing, uploading, or loading onto a phone. Converting to MP3 drops the file to a fraction of the size while keeping the sound close, so a common workflow is to keep the AIFF as your master and hand out the MP3.
