About the formats
AAC, the successor to MP3
AAC is the lossy audio codec that replaced MP3; this file is “raw” AAC, without a container (ADTS).
Strengths: At the same size it sounds better than an MP3 and almost every device understands it.
Limits: Without a container it holds no artwork or tags, and some programs prefer M4A.

Frequently asked questions
Is my WAV uploaded to a server to turn it into AAC?
No. The WAV to AAC conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.
Do I lose quality going from WAV to AAC?
A little, because AAC is lossy; at 192 kbps or more the difference is hard to hear.
Is there a size limit?
Up to 2 GB on desktop and 500 MB on mobile (less on low-memory devices), and up to 12 hours of audio on desktop. If it is over, you are told before it starts.
Can I convert several WAV files at once?
Yes. Drop as many WAV files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each AAC or all of them in a ZIP.
