How this works — and why it's private
- Both SRT and VTT are auto-detected — paste either, pick the target format, and you get back the other.
- The time shift slider adds or subtracts seconds from every cue, ideal when captions are a few seconds out of sync.
- Files are parsed and rebuilt in your browser. Nothing is uploaded, nothing is logged.
