Both are plain text files with numbered or labelled cues and start and end times. VTT (WebVTT) starts with a WEBVTT line, uses a dot before the milliseconds (00:00:01.000) instead of a comma, and supports cue positioning and styling. HTML5 video players need VTT; most editors and YouTube take either.
No. The file is read and converted by your browser on your own device. Nothing is sent to a server.
Yes. Line breaks, bold, italic and underline are kept. SRT colour tags (<font>) and position codes such as {\an8} have no WebVTT equivalent in the cue text, so they are removed.
One file at a time. Each conversion takes under a second, so you can drop the next file straight away.
Conversion copies the timings exactly, so the offset was already in the source file. Use the subtitle shifter to move every subtitle earlier or later by the same amount.
