What can this tool do?
Subtitles out of sync, need to shift earlier or later, convert SRT to VTT, or merge several files — this tool handles it all: paste or choose a subtitle file to parse, review cues with their timings, apply an offset in seconds or a scale ratio, then download or copy in your chosen format. Everything runs locally.
FAQ
Are subtitles uploaded?
No. Parsing and conversion happen in your browser; subtitle text never leaves your device.
What about negative times after shifting?
Any start time pushed before 0 is clamped to 0, so players won't choke on the file.
