No. Everything runs in your browser - your file never leaves your device. How this is verifiable
WebVTT (.vtt) is the subtitle format of the web and comes, for example, from online video players or the export functions of subtitle editors. Many classic desktop players, editing programs and device software, on the other hand, expect the older, simpler SRT (SubRip). This tool converts your .vtt file into an .srt so it works everywhere WebVTT is not accepted.
During conversion the tool removes the WEBVTT marker line and any position or style hints that SRT does not know, and numbers the subtitles sequentially from one - exactly as the SRT specification requires. The milliseconds are switched from the dot to the comma that is usual in SRT. Start and end times and the actual text stay unchanged.
Everything happens strictly locally in your browser; the subtitle file is not sent to a server and nothing is stored. If the file contains no recognisable timestamps - for instance because it is not a real WebVTT file at all - you get an honest error message instead of an empty output.

Limitations: SRT has no positioning, regions or style blocks - such WebVTT specialities are deliberately dropped during conversion because the target format cannot represent them. Timings and text are preserved and the subtitles are renumbered. No language translation takes place.
No. The conversion is purely local in the browser; the .vtt file does not leave your device.
SRT requires a sequential number before each subtitle. WebVTT does not have that, so it is generated from one during conversion.
Yes, because SRT has no positioning. Timings and text are fully preserved, however.
Yes. SRT is the most common subtitle format and is read by VLC and almost every player.
