LRC Offset Editor
Shift all timestamps in an LRC file or edit individual lines. Runs in your browser.
What you can do
Apply a global offset in milliseconds — positive moves lyrics later, negative moves them earlier. The timestamp table is editable line by line, so you can fix a single out-of-sync entry without touching the rest.
Preview and save
The result is shown as plain LRC text and updates live as you type. Download when it looks right; the file is renumbered in time order.
Privacy
The file is parsed locally in your browser. Nothing is uploaded.
