How to use

- Tidy up any wording directly in the box, then download the updated .srt.
FAQ
Is my subtitle file uploaded anywhere?
No. Everything happens in your browser — the file is read and edited locally and never sent to a server, so it works offline and stays private.
What does shifting do?
It moves every timestamp in the file by the number of seconds you enter — perfect for captions that appear a little early or late. A positive number delays them; a negative number moves them earlier (never before zero).
Can I edit the wording too?
Yes. The whole subtitle file is editable in the box, so you can fix typos or rewrite lines before downloading. The format stays standard SRT.
