Free SRT Subtitle Time Shifter
The SRT Time Shifter delays or advances every timestamp in a subtitle file by a fixed offset so it lines up perfectly with your video. Paste or upload an SRT file, set the shift, and download the corrected file.
How to Use
Paste your SRT content or load a .srt file, enter the offset in seconds (positive to delay, negative to advance), then download the shifted file.

- Auto-detects negative timestamps and clamps at zero
- Keeps all original formatting intact
