KaraFun Player allows you to synchronize your offline playlists so you can play the tracks in these playlists without an internet connection.
You just need to enable the "Offline" option and wait during the synchronization of files between KaraFun Player and your computer.
If you have a Premium subscription, you can download up to 1000 tracks for offline use. If you want to download the entire catalog, you need a KaraFun Professional subscription.
Your playlist is only available from the computer you used to create it, but you can check out our article on transferring your playlists between your computers.
For your information: The average size of a synchronized offline track is 5MB.
