Subtitle Time-Shift Tool
Shift every cue in an SRT/VTT forwards or backwards by a precise number of seconds to fix subtitles that run early or late.
When subtitles are perfectly paced but uniformly early or late (a common result of a different release cut or a missing intro), a constant shift fixes the whole file. Enter the offset in seconds — positive to delay, negative to advance — and download the corrected SRT.
🔒 Subtitles are processed entirely in your browser — never uploaded.
