Shift subtitles without changing their text
This tool changes only the two timestamps on each SRT cue line. Cue numbers, subtitle text, line breaks and optional timestamp settings are preserved, so the downloaded file can be opened directly in a media player or subtitle editor.
Offset examples
+2.5seconds delays every cue by two and a half seconds.-350milliseconds moves every cue 350 ms earlier.- If an advance would create a negative timestamp, that timestamp is safely clamped to
00:00:00,000.
Local-only: file contents and pasted subtitles stay in this browser tab. No subtitle data is sent to a server.
