Subtitle toolkit — shift, convert, renumber

Out-of-sync captions, SRT↔VTT conversion, broken numbering — fixed in your browser, nothing uploaded.

Times are shifted, cues renumbered from 1, and format converted (comma↔dot decimals, WEBVTT header). Need captions from scratch? Generate SRT/VTT from audio · check pacing with the reading-speed checker · what is SRT?
