Answers before you open the player.

MP3+G means an MP3 audio file plus a CDG graphics file. Together they make a karaoke track with backing audio and timed lyric graphics.

A CDG file stores the low-resolution lyric graphics used by many karaoke tracks. ZipSing renders those graphics to a browser canvas.

Yes. ZipSing can open local MP4 karaoke videos directly or from a ZIP, using the same queue and fullscreen controls.

No. ZipSing opens your karaoke files locally in your browser. Your media files are not sent to the ZipSing server.

Yes, subject to each phone browser's file and fullscreen behaviour. Android Chrome is the most capable mobile target; iPhone Safari has some fullscreen limitations.

Yes. ZipSing is designed for modern Chrome and browser-only devices such as Chromebooks.

The player includes an app-shell service worker. You still choose your local media files each time unless a future version adds optional local library features.

ZipSing needs a ZIP containing a playable MP3+G pair or an MP4 karaoke video. Password-protected ZIPs, missing files, huge files, or corrupted archives may be rejected with a clear error.

Not yet. Proper karaoke key change needs high-quality browser audio processing and testing, so it remains planned research.

Yes. ZipSing now supports a local queue, singer names, reordering, marking tracks sung, skipping, and playlist metadata export/import. Browser security means exported playlists do not include your media files.

ZipSing can be useful as a browser player, queue, or backup, but it is not yet a full KJ hosting suite. You are responsible for testing your own setup and file rights.

No. ZipSing does not provide, host, or sell karaoke tracks. It is only a player for your own files.

A media player is legal to use with files you have the rights to use. Do not use ZipSing with illegally copied or infringing karaoke files.
