About this SRT merger
There are two common reasons to merge subtitle files. A film split into parts, or a series of clips joined into one video, needs its subtitles joined too, with the second file’s timings moved to start where the first one ends. Dual-language viewing or adding forced captions for signs needs both files on the same timeline instead, so that lines appear together. This merger does both. In sequential mode it shifts the second file automatically and lets you add a gap; in overlay mode it keeps the original timings, optionally offset, and sorts everything by start time. The merged file is renumbered and keeps formatting tags.
How to merge SRT files
- Add both files. Paste each SRT file into its box or use Open file, or press an example.
- Choose the merge mode. Pick One after the other for split videos or Same timeline for two languages or extra captions, and add an offset if needed.
- Press Merge subtitles. Copy the result or download merged.srt and load it in your player.
Frequently asked questions
How do I join subtitles for a video in two parts?
Use One after the other. The second file’s timings are moved so its first line starts right after the first file’s last line ends, plus any offset you enter for a gap.
How do I show two languages at once?
Use Same timeline. Lines with the same times appear together, usually one above the other. Some players show only one at a time if they overlap exactly.
What does the offset do?
It moves the second file by that many seconds. In sequential mode it adds a gap after the first file; in overlay mode it shifts the second file to fix a timing difference. Negative values move it earlier.
Are the subtitles renumbered?
Yes. The merged file is numbered from 1 in time order, so players read it without errors.
Can I merge more than two files?
Merge two, copy the result into the first box, add the next file in the second box, and merge again.
