Why convert Opus to ALAC?
Opus — The best small-size sound. Used for podcasts, voice chat, and the web.
ALAC — Apple's perfect-quality format. Built in on iPhone, iPad, and Mac.
One thing to keep in mind: a Opus file has already had some of its sound removed to keep the file small. Saving it as ALAC keeps what's there but cannot put the missing sound back. This kind of conversion is for when a program or app needs a ALAC file, not for making the song sound better.
All of this happens right inside your web browser. Your file stays on your phone or computer the whole time.
Frequently asked questions
