Supported subtitles

Supports plain, multiline cues. Remove styles, regions, comments, inline markup and cue settings before conversion. SRT exports renumber the cues.

How it works

A timing offset moves the start and end of every cue by the same amount. A positive offset displays the captions later and a negative offset displays them earlier.

Assumptions and limits

Use text-based subtitles. Files that depend on advanced WebVTT styling and positioning need a subtitle editor that supports those features.

Guide and examplesConvert SRT → VTT, VTT → SRT or shift all timestamps

Paste SRT or WebVTT captions, or open a file and choose its encoding. Use plain text cues in ascending start-time order, separated by blank lines.
Choose VTT for SRT → VTT, SRT for VTT → SRT, or TXT to extract the words without timestamps. Add a positive shift for later captions or a negative shift for earlier ones.
Convert, review the output and any overlap count, then copy or download it. A shift that would place a cue before zero is rejected.

To convert back without another timing change, choose SRT and a zero shift. SRT cues are renumbered. Limits are 1 MB of text and 5,000 cues. Styles, regions, comments, inline markup and cue positioning settings are not supported; overlaps are reported, not automatically repaired.
