How to merge subtitles
- Select two to ten UTF-8 SRT or VTT files. Review the displayed file order.
- Choose original timelines, append clips, or bilingual pairs with identical cue times.
- Inspect overlaps and the merged cues, make corrections and download the result.
How does append mode handle timestamps?
The first file keeps its timing. Each following file is shifted so its earliest cue starts after the preceding file’s latest cue, plus your chosen gap. Clip durations are not inferred.
Can I merge two languages?
Bilingual mode requires exactly two files with equal cue counts and identical start/end times for each pair. Mismatched tracks must be synchronized first; this tool will not guess matches.
