FAQ

Frequently Asked Questions

Yes. It is completely free, with no sign-up and no limit. The conversion runs in your browser, so there is no server cost and nothing to pay for.

No. All parsing and conversion happen locally in your browser using JavaScript. Your subtitle text never leaves your browser, which keeps private transcripts private.

SRT and VTT are both timed caption formats. SRT uses comma decimal separators (00:01:02,500) and numbered cues, while WebVTT starts with a WEBVTT header and uses period separators (00:01:02.500). This tool converts between them and keeps the timings intact.

Yes. Choose TXT as the output to strip the cue numbers and timestamps and keep just the spoken text, which is handy for pasting into a document or word counter.

You can export them from most video editors and caption tools. With LiteScribe you can transcribe any audio or video and export an SRT directly, then convert it to VTT and fine-tune it with this converter.
