How to use it
Your file, ready for its next step.
- Open your subtitles. Choose a file, paste SRT or VTT, or try the sample. No account needed.
- Choose your changes. Adjust the options and run the tool. Read any warnings before continuing.
- Check and download. Review the output and save a new file. Your original stays unchanged.
Worked example
Merge subtitles, in practice.
If part one is 60 seconds long, append part two with an offset of 60. A cue at 2 seconds in part two becomes 62 seconds.
Before you download
Use the actual first video duration for an append offset. The last subtitle may end before the video does. Combined tracks can intentionally overlap.
These tools work with existing SRT and WebVTT files. If you need captions from audio, open the video caption editor instead. Files are limited to 5 MiB and 20,000 cues per input. Results stay in this tab until you copy or download them.
Questions
A few useful answers.
Can I merge two languages?
Yes. Combine keeps both tracks on the same timeline and sorts cues by start time. The output contains both texts as separate cues.
Are my files private, and what are the limits?
Processing stays in this browser without an account. Each subtitle input is limited to 5 MiB of UTF-8 text and 20,000 cues. Session recording is disabled here. Closing or reloading the page clears your work.
