Line timing, not word-level fill
The preview sorts every `[mm:ss.xx]` stamp and shows which line is active as you drag the slider. That is line-level timing: it can move or highlight a whole row.
Word-level Karaoke fill is a stricter dataset. This tool never fabricates word timing from line stamps, and lines without timestamps are treated as plain text.
Everything stays in the browser
Paste is parsed on your device. Nothing is uploaded, stored, or sent to a lyrics API.
Use it to sanity-check an LRC file before you rely on it in a scene, without exposing the file or any account.
Use the tool
Paste LRC text to preview line-level timing locally. Word-level Karaoke is never fabricated, and untimed lines stay plain text.
Frequently asked questions
Does this create Karaoke timing?
No. It only reads line-level timestamps and never invents word-level fill.
Is my LRC uploaded?
No. Parsing runs locally in your browser.
What if a line has no timestamp?
It is treated as plain text and is not given a fake time.
