Frequently Asked Questions
How much smaller will my AIFF get?
AIFF is uncompressed PCM — CD-quality stereo runs about 10 MB per minute. The MP3 output lands around 1.4 MB per minute, an ~86% reduction that's transparent to almost every listener.
When should I keep AIFF instead?
Keep AIFF (or WAV) while you're still editing, mixing or mastering — every lossy re-encode costs a little quality. Convert to MP3 only for the final version you distribute.
Is it safe to convert audio bounces online?
Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so audio bounces never leave your device — you can even disconnect from the internet after the page loads and it still works.
Is this converter really free?
Yes — completely free, with no sign-up, no watermarks, and no file-per-day limits. Because conversion happens on your own device, there are no server costs to pass on to you.
