Import your MP3 files once and play them anytime — even with no internet connection. Everything is stored right here on this device; nothing is ever uploaded anywhere.
Owning a file outright and renting access to one through a subscription are different things — this is for people who'd rather keep doing the first.
No. Every MP3 you add is copied straight into your browser's own local storage on this device. Nothing is ever sent to a server — there's no upload step at all.
Yes. Once you've opened the page and added your tracks, playback needs zero network from then on — your library is read straight out of local browser storage, not fetched over the internet.
No — the library lives in this browser's local storage on this specific device only. It doesn't sync across devices or browsers, and clearing this browser's site data will erase it, same as any other local app data. There's no cloud backup.

Yes — click any track's name to rename it, and use the search box to instantly filter your library by name.
This library is built around MP3 specifically — other audio formats may not import or play correctly.
Yes — drag and drop multiple files, or a folder of MP3s, at once instead of adding them one by one.
Only briefly while each file copies into local storage. Playback itself stays lightweight no matter how large your library grows.
