SRT Merger

You have two SRT files and need them as one. The SRT Merger combines them and renumbers the cues.

Choose Concatenate to place file B right after file A, or Merge by time to interleave both files chronologically when they overlap. Either way every cue is renumbered sequentially and the wording and timing are untouched. Paste both files and merge.

• Two modes: concatenate or merge by time.
• Auto-renumber: sequential indices.
• Time sort: chronological order for overlaps.
• Safe parsing: empty blocks skipped.
• Lossless: text and timing preserved.
• Private: runs in your browser.

1. Paste SRT A and SRT B (samples preloaded).
2. Pick a merge mode.
3. Click Merge SRT and copy or download.

Example 1 — Two parts. Merge part 1 and part 2 of a film.

Example 2 — Overlap. Combine a corrected segment with the original in time order.

Example 3 — Bilingual base. Merge before joining languages.

• One file: simpler delivery.
• Correct order: time mode handles overlaps.
• Clean numbers: renumbered automatically.
• Lossless: content preserved.
• Private: nothing uploaded.
