Merge SRT & VTT Subtitle Files
Combine two to ten subtitle files into one SRT or VTT. Set a time offset for each file and review the combined timeline.
About Merge Subtitles
Bring subtitle files from separate recordings or edits into one timeline. Files keep their original timestamps unless you enter an offset. For consecutive video parts, set each later file's offset to that part's actual start in the combined video.
What to expect
- Open 2–10 supported subtitle files, each up to 2 MB. The combined output is limited to 20,000 cues.
- Cues are sorted by start time and renumbered. Repeated text and overlapping cues are kept.
- A subtitle's last end time is not necessarily the end of its video. Enter offsets from the actual combined video, not a guessed duration.
- This combines tracks; it does not translate or combine two languages into a single bilingual cue.
How to use Merge Subtitles
- 01
Add your subtitle files
Choose two to ten files. You can mix SRT, VTT, ASS/SSA and SBV.
- 02
Place them on the timeline
Leave offsets at zero to combine tracks that share a timeline. For consecutive parts, enter the start of each part in seconds.
- 03
Merge and review
Preview the ordered captions, check overlap warnings, and download one SRT or VTT.
Frequently asked questions
Will the second file be appended automatically?
No. An automatic offset based on the last caption could remove silence or misalign later video parts. Enter the actual start time of each part; files with zero offsets share the same timeline.
Are repeated subtitles removed?
No. Repeated lines may be intentional. Every caption is retained and sorted by time, including overlapping captions.
Can I merge two languages?
You can put their cues in one file, but this tool does not align translations into bilingual pairs. Overlapping cues may display differently in different players.
