    About This LRC Merger

    This merge LRC files online tool is designed for producers, karaoke curators, streamers, and K-pop fans who need clean synced lyrics in a hurry. Unlike bulky desktop software, everything happens inside your browser, so no uploads ever leave your device. We benchmarked the most popular lyric combiner tools on Google, Reddit, and fan forums, then stripped away the clutter to focus on speed, clarity, and accuracy. The result is a mobile-first experience with smart timestamp deduplication, metadata preservation, an adjustable global offset dial, and rapid export options.

    Core Web Vitals were a priority during development, so every interaction stays lightning fast. The interface borrows Kadence-inspired styling with soft gradients, rounded edges, and subtle motion to feel premium while remaining accessible. Live timeline filtering, CSV analytics, and shareable permalinks give collaborators instant context, so you can focus on polishing performances instead of fighting formatting.

    How to Use

    Start by dragging multiple LRC files into the upload card or click to browse your folders. Choose how duplicate timestamps are handled: keep the latest revision, freeze the earliest, or blend them into one hybrid lyric. Toggle metadata inclusion if you want the combined file to retain title, artist, or album tags. Use the global offset field to nudge every timestamp forward or backward when two versions drift out of sync, then watch the updates land in the output panel.

    From there, copy the result to your clipboard, download a ready-to-use .lrc, or export a CSV timeline for spreadsheet reviews. Apply the instant timeline filter to zoom in on tricky phrases while retaining the full context. Need to collaborate? Generate a shareable permalink that stores the merged output in the URL hash, so teammates can reopen the exact same version without relying on cloud storage.

    Tips for Best Results

    • Ensure each lyric line includes timestamps like [01:23.45] for precision merging.
    • Dial in the global offset field to correct drift when one track starts a little early or late.
    • Use the “Combine into one line” option when duet parts should play simultaneously.
    • Export the timeline CSV to spot gaps or overlaps in milliseconds before uploading to a karaoke player.
    • Filter the live timeline to audit harmonies or translations without losing the full lyric context.
    • Leverage the permalink feature to maintain version history when iterating with collaborators.

    FAQs

    Are my lyrics uploaded to a server?

    No. Every merge happens locally in your browser, so your lyrics stay private.

    Can I merge files with different encodings?

    Yes. The tool reads UTF-8 by default and gracefully handles typical ANSI encodings found in older karaoke files.

    What makes this tool faster than competitors?

    We use lightweight vanilla JavaScript, no trackers, and efficient timestamp parsing to keep load times under two seconds even on mobile.

    How can I fix sync drift between files?

    Use the global offset field to apply millisecond-perfect shifts across every timestamp, then review the filtered timeline to confirm harmonies and cues line up.

    How do I share the merged lyrics with others?

    Click “Create shareable permalink” to copy a URL hash that reconstructs the merged file on any device.
