How to merge subtitle files
Select local SRT or WebVTT files, arrange them in sequence, and combine their cues into one ordered subtitle stream. Subtitle Merger also lets you set a timestamp offset for each file, choose overlap and duplicate-cue policies, and select the output format. You can preview conflicts before exporting, and the files are handled locally in your browser.
Use Subtitle Merger with SRT and WebVTT files
Open Subtitle Merger when several local subtitle files need to become one ordered stream. It accepts SRT and WebVTT inputs, then combines their cues according to the sequence you set. The selected order is explicit, so file names and selection order do not decide the result.
- Choose the order of the subtitle files.
- Set a separate timestamp offset for each file when its cues need to move earlier or later.
- Pick the overlap policy and duplicate-cue policy before exporting.
Adjust subtitle timing and cue conflicts
A timestamp offset applies to one file at a time, so you can move that file's cues earlier or later while leaving the other inputs unchanged. The overlap policy controls cues that occupy the same time. The duplicate-cue policy covers repeated cues.
Subtitle Merger can preview conflicts before export. Check the preview when files contain overlapping or repeated cues, then change the sequence, offsets, or policies before exporting the combined stream.
Set cue text, styling, and metadata options
Choose a cue-text separator for text joined when cues are combined. You can also set how Subtitle Merger handles styling and metadata from the source files. Select the output format after setting those options.
For example, part-1.srt + part-2.srt can become one ordered subtitle file after you set the second file's offset, overlap policy, cue separator, and output format. The result depends on the files, their timestamps, and the policies you choose in Subtitle Merger.
Where merged subtitles come up
- Two SRT files need to be combined in a specific sequence. Set the order, adjust the second file's timestamp offset, and export one stream for review.
- WebVTT files contain overlapping cues. Preview the conflicts, choose an overlap policy, and check the combined file in the selected output format.
- Subtitle files contain repeated cues or different text formatting. Choose a duplicate-cue policy, set the cue-text separator, and inspect the merged result.
When to use Subtitle Merge Tools
Use Subtitle Merge Tools when you need to combine subtitle files into one ordered stream. Open Subtitle Merger to set file order, per-file timestamp offsets, conflict policies, cue text, styling, metadata handling, and output format. For conversion, retiming, styling, splitting, or validation, open Subtitle Tools.
Frequently asked questions
How do I merge SRT files?
Open Subtitle Merger, select the local SRT files, choose their sequence, and set any per-file timestamp offsets. Review the overlap and duplicate-cue policies, preview conflicts, and export the combined stream.
Can I merge WebVTT subtitle files?
Yes, Subtitle Merger accepts local WebVTT files as inputs. Set their order, timestamp offsets, overlap and duplicate-cue policies, styling and metadata handling, then select the output format.
How are subtitle overlaps handled?
Choose an overlap policy before exporting. Preview the conflicts when cues from different files occupy the same time.
Can I preview subtitle conflicts before exporting?
Yes, you can preview conflicts before export. Check repeated or overlapping cues after setting the file order and timestamp offsets.
