Merge two SRT subtitle files into one.
Join subtitles from consecutive clips without manually renumbering cues or recalculating every timestamp. Choose the pause between files, inspect the combined result, and download a clean SRT.
How this tool works
- 01
Paste both SRT files
Put the subtitles for the earlier clip first and the subtitles for the following clip second.
- 02
Choose the transition gap
Enter how many seconds should pass between the last cue in file one and the first cue in file two.
- 03
Review and download
Check the shifted timestamps, then download one sequentially numbered SRT file for the combined video.
Practical guide
What to know before you download
Merge subtitles in the same order as the video
The first SRT should belong to the first clip on the combined timeline. The merger keeps every cue in that file at its original time. It then shifts all cues from the second file together so its earliest cue begins after the final cue in file one. This is designed for two clips that will play consecutively, not for mixing separate languages or speakers over the same footage.
Set the gap from the actual edit
Use zero seconds when the second clip starts immediately after the first caption ends. Add a gap when the edit contains a pause, title card, silent transition, or extra footage between clips. The value is measured from the end of the last cue in the first file to the start of the first cue in the second file. If the joined video includes a five-second transition, enter five rather than guessing from the original cue numbers.
What the merger changes and preserves
Cue text and each cue's duration are preserved. The second file receives one consistent time offset, and the final output is renumbered from the beginning. Because the result is a portable SRT file, advanced styling or positioning from another subtitle format is outside the scope of this tool. Always scan names, punctuation, line breaks, and synchronization after combining files.
Preview against the final combined video
A mathematically correct merge can still be wrong for the finished edit if the clips were trimmed, reordered, or separated by a transition of a different length. Import the downloaded SRT into the player or editor that contains the final video. Check the last cue before the join, the first cue after it, and a later cue. If every cue is consistently early or late, use the timing shifter. If the error grows over time, the source needs retiming rather than a single offset.
Questions about this tool
Does this SRT merger upload my subtitle files?+
No. The pasted subtitle text is parsed, shifted, combined, and downloaded in your browser. You do not need to upload a video or create an account.
Will the second file keep its cue spacing?+
Yes. Every cue in the second file receives the same offset, so its internal timing, gaps, and cue durations remain unchanged.
Can I use the tool for overlapping subtitle tracks?+
No. It places one SRT after another for consecutive video clips. It is not a track mixer for bilingual or overlapping captions.
What if my combined video was trimmed?+
Set the transition gap from the finished timeline and preview the result. If either source clip was trimmed internally, those captions may need separate timing corrections before or after the merge.
