VTT to SRT converter

Convert a .vtt file to SRT, adding the numeric cue indices SRT requires and switching the millisecond separator back to a comma.

Choose an .srt or .vtt file - it stays on your device, nothing is uploaded

Subtitle files are plain text, so this runs entirely in the page - no upload, no processing engine to load.

Worth knowing

SRT is what most video editors and upload forms accept; VTT often is not.
WebVTT cue settings and positioning hints are dropped, because SRT has nowhere to put them.

Koldflux generates and styles captions as part of its render pipeline.
