Lyrics Timestamp Tool — Free LRC Generator & SRT Maker
Create perfectly synchronized lyrics in your browser. Load an audio file, press Tab on each word or line as it's sung, and export a word-by-word LRC, line-by-line SRT or VTT file — or embed the timed lyrics straight into your MP3 via the SYLT frame. No upload, no account, completely free.
Press Tab to stamp each word while playing, and press Enter at the end of every line — the tool automatically treats only the longer pauses as instrumental breaks, so it's always safe to press it. ↑ / ↓ move between words; each line's time is clickable (jump to it) and the Re-stamp button clears that line so you can time it again.
How to Timestamp Lyrics
- Load audio — drop in any audio file (MP3, M4A, WAV, OGG, FLAC).
- Add lyrics — paste them (one line per line) or import an existing LRC/SRT to re-time.
- Play & stamp — press Play, then hit Tab on each word or line as it's sung. The active token advances automatically. Press Enter to mark a line break.
- Adjust — use ↑/↓ to move between words, fine-tune a word with the time box, or apply a global offset to shift every stamp at once. Ctrl/Cmd+Z undoes the last change.
- Preview — click Preview to play back karaoke-style and make sure the timing feels right.
- Export — download LRC / SRT / VTT, or embed the synced lyrics into your MP3 via the SYLT frame.
Why Use This Lyrics Timestamp Tool
This free online lyrics timestamp tool turns plain text lyrics into time-coded LRC or SRT files without installing anything. It's built for music producers, karaoke creators, lyricists, translators and anyone who needs synced lyrics — whether for a music player that displays word-by-word LRC, a video editor that imports SRT subtitles, or an MP3 collector who wants lyrics that scroll with the song.
- Word-by-word (enhanced) LRC — the exported LRC includes per-word time tags (
<mm:ss.xx>) so supported players highlight each word in time, not just each line. - Line-by-line SRT & VTT — export standard subtitle files for music videos, sing-along videos, podcasts or any timed text overlay.
- Embed SYLT + USLT into MP3 — instead of shipping a separate .lrc file, write the synchronized lyrics straight into the audio file's ID3 tags. Compatible players like Poweramp, foobar2000 and Apple Music display them automatically.
- 100% private — the audio file and your lyrics never leave the browser. There is no upload, no server-side decoding for timing, and no account required.
- Smart helpers — playback speed control for tricky passages, global offset to slide every stamp at once, undo, autosave so you can close the tab and come back, and a karaoke Preview mode.
- CJK-friendly tokenizer — Latin words stay whole, while Chinese, Japanese and Korean characters are split per character so karaoke timing stays natural in any language.

Frequently Asked Questions
What is an LRC file and how is it different from SRT?
An LRC file is a lyrics synchronization format that stores a timestamp before each line or word, like [00:12.34]La la la. SRT is the standard subtitle format used by video players. This tool can export both: word-by-word (enhanced) LRC for music players and line-by-line SRT for video subtitles, plus WebVTT for the web.
Is the Lyrics Timestamp Tool free and private?
Yes. The tool is completely free and runs entirely in your browser. Your audio file and lyrics never leave your device — there is no upload, no server-side processing, and no account required.
How do I time lyrics with the Tab key?
Load an audio file, paste your lyrics and click "Load lyrics", then press Play. While the song plays, press Tab on each word as it is sung — the tool records the current playback time as that word's timestamp and advances to the next one automatically. Press Enter to mark the end of a line, and use Ctrl/Cmd+Z to undo mistakes.
Can I embed synced lyrics into an MP3 file?
Yes. Click Embed into MP3 (SYLT) and the tool writes the timed lyrics directly into the MP3 using the ID3 SYLT (synchronized lyrics) and USLT (unsynchronized lyrics) frames. Many music players — such as Poweramp, foobar2000 and Apple Music — can then display the lyrics in time with playback.
Which audio and lyrics formats are supported?
The tool loads MP3, M4A, WAV, OGG, OGA, FLAC, AAC and WebM audio. You can paste plain-text lyrics or import an existing LRC or SRT file to re-time or edit it. Exports are available as LRC (word-by-word), SRT (line-by-line), VTT or an embedded MP3.
Does it work on mobile and offline?
Yes. The tool works in any modern mobile or desktop browser (Chrome, Safari, Firefox, Edge) and, once the page has loaded, can run offline because all processing is client-side. Your timed session is autosaved to the browser so you can return later and restore it.
