Free online subtitle tools
Convert, re-time and clean up subtitle files right here in your browser. Your files never leave your device. To make subtitles from a video in the first place, use the free Captionshaper app.
Convert SRT to VTT (or VTT to SRT)
Drop either format and get the other. VTT is for HTML5 video on websites; SRT is for video editors and YouTube.
Shift subtitle timing
Subtitles running early or late? Move every caption by the same number of seconds.
Subtitles to plain text
Strip the numbers and timestamps from an SRT or VTT file and get a clean transcript.
Need subtitles from a video?
Captionshaper listens to your video and writes word-timed captions on your own computer, then exports SRT, VTT or a video with the captions burned in.
