AIFF (.aiff) · Max 20 MB
Traditional online converters upload your file, process it on a remote server, and send it back. That's slow, insecure, and wasteful. AudioUtils eliminates the upload entirely.
The converter uses WebAssembly to run a compiled audio engine in your browser tab. It reads your file locally, converts it locally, and saves the result locally. The network is never involved.
This matters for sensitive audio. Unreleased music, legal recordings, private conversations. With AudioUtils, your files stay yours. AIFF is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
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.
