SRT to VTT converter

Both list each subtitle with a start time, an end time and its text. SRT numbers every subtitle and writes milliseconds after a comma (00:00:01,000); WebVTT starts with a WEBVTT line, uses a dot (00:00:01.000) and can add positioning, styling and speaker tags. Web players such as HTML5 video need VTT, while editing apps and most TVs read SRT.

Bold, italic and underline (<b>, <i>, <u>) work in both formats and are kept. VTT positioning, speaker tags, CSS classes, NOTE and STYLE blocks have no SRT equivalent, so they are removed and the text is kept.

A slow drift usually means the video was converted to another frame rate, for example 23.976 fps film played at 25 fps in Europe. Pick that change under Frame rate change; to fix a constant delay, use Shift instead.
