About Convert subtitles
- What does Convert subtitles do?
- Convert between SRT and VTT subtitle files, and fix timing that is early or late.
- Who is it for?
- Creators preparing clips for a platform, teams that record meetings and need the content in writing, and anyone whose video file is too large to send.
- Is it free?
- Yes. Convert subtitles is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
- Is it safe to use with confidential files?
- Yes, and not because we promise to behave. Convert subtitles never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.

- Input: SRT, VTT. Output: SRT, VTT.
