When to use Subtitle Merger
Use Subtitle Merger to join caption files from separate scenes, language segments or recording parts into one subtitle track. It is useful when the video is continuous but the captions were exported in multiple files.
How to use this tool
- Add the subtitle files in playback order.
- Set the output format and timing option shown in the tool.
- Check the join between files and inspect the first, middle and final cues.
- Download the merged track and test it against the video before publishing.
Subtitle timing and privacy
Subtitle formats support different timing precision, styling, positioning and encoding rules. A conversion can remove features the destination format cannot represent, so review timestamps before publishing. Supported processing runs locally in the browser when available.
