Fix captions without desktop software
Captions a second or two out of sync? Typo in a line? You don't need Aegisub or a video editor for small fixes. Load your .srt, edit the text inline, and shift every cue forward or back by a set number of seconds to re-sync with the video — then export a clean file.
Local and private
Editing happens in your browser. The file isn't uploaded, so it's instant and safe for confidential or client subtitles.
Common uses
- Re-sync captions that drift after a re-encode

- Shift timing after trimming an intro off a video
FAQ
Can I shift only some cues?
This tool shifts all cues by the same offset, which fixes the most common 'whole track is off by N seconds' problem. For per-cue retiming, export and open in a desktop editor.
Is the file uploaded?
No. All editing is local to your browser.
