AIFF (.aiff) · Max 20 MB

Most online converters upload your file to a remote server, process it in a queue, then send it back. That round trip takes minutes. AudioUtils skips all of it. The conversion engine runs on your device via WebAssembly.

Speed depends on your device, not your internet connection. A modern laptop converts a 5-minute audio file in 2-3 seconds. Even phones handle it in under 10 seconds. No progress bar that stalls at 99%.

AIFF is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. Fast doesn't mean low quality. The encoder uses the same settings as desktop tools like FFmpeg. You get full quality at browser speed.

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.
