Subtitle Time Shift Tool
Move SRT or VTT timestamps forward or backward without changing the caption text.
Ready. Paste a subtitle file, set an offset, and shift the timestamps.
Fix subtitle sync problems fast
If subtitles start too early or too late, you usually do not need to rewrite the file. A time shift moves every cue by the same amount while preserving the content and structure of the original subtitle file.
Supports both SRT and VTT
The tool auto-detects the subtitle format, keeps the same output format, and prevents timestamps from dropping below zero when shifting backward.
Private browser-only processing
Your captions never leave the page. The timing math runs locally using JavaScript only.
