SRT Offset Tool
Shift subtitle timing forward or back, locally.
Runs entirely in your browser. Nothing is uploaded.
How to use
- Paste your SRT or load a file.
- Enter an offset in seconds, or nudge with the step buttons.
- Apply, then copy or download the shifted subtitles.
Examples
- Pull every subtitle a second earlier when the captions run late.
- Push timing back to line up with a re-edited cut.
- Nudge by a tenth of a second to fine-tune sync against the audio.
Frequently asked questions
Does it shift every cue?
Yes, the offset moves all start and end times by the same amount, preserving the gaps between cues.
What if the offset goes negative?
Times are clamped at zero, so subtitles never start before the file begins.
Is my file uploaded?
No. The whole tool runs in your browser and nothing is uploaded.
