Convert MP3 to ALAC

How it works

Why convert MP3 to ALAC?

Convert MP3 to ALAC (Apple Lossless). Note: MP3 is already lossy, so the output won't sound any better — it just gets wrapped in Apple's lossless codec. Useful when your library standardises on .m4a but you have MP3s.

Is my file uploaded anywhere?

No. poqpoq is a static site — the page you're looking at is a bunch of JavaScript your browser downloaded once. It runs entirely on your device. There is no upload endpoint. When you open your browser's Network tab during a conversion, you'll see zero requests going out.
