LRC Validator
Check a Lyrics File (LRC) for malformed timestamps, broken cue structure and out-of-order timings before a player or platform rejects it. Runs entirely in your browser.

Nothing to check yet
Paste a LRC file on the left, drop a .lrc onto it, or load the sample. Results appear here as you type — there is no button to press.
What the validator checks
Spec-strict parser
We follow the LRC reference grammar — any deviation is flagged.
Helpful error messages
Each error names the line number and what's wrong, not just 'parse failure on line 42'.
Privacy-first
Validation runs in your browser. Use it on unreleased subtitles without leaking them anywhere.
Format mismatch detection
Pasted SRT into the LRC validator? We'll suggest switching to the right one before you waste time debugging.
What people use it for
Pre-delivery QA
Catch broken subtitles before sending to a client or platform that will reject the whole batch.
Player crash debugging
When a player rejects a file with a generic error, validate here to find the actual offending line.
Mass-cleanup
Identify which files in a folder need fixing — drop each one in for a fast pass/fail.

Questions
What does the LRC validator check?
Structure and timing: that cues parse, that timestamps are well-formed and in a sensible order, and that the file's required blocks are present. It reports problems — it does not rewrite your file.
My file plays fine but shows errors. Why?
Players are forgiving and often guess past malformed cues. Another tool in the chain — an encoder, a platform's ingest, a different player — may not be. The validator reports what the specification requires, not what one player tolerates.
Is my file uploaded anywhere?
No. Validation runs entirely in your browser; the file never leaves your device.
