I strip timestamps to get clean dialogue scripts for translation quotes.
Uploaded a two-hour recording during lunch — the transcript was waiting before I finished my coffee. The accuracy genuinely surprised me.
Our legal team approved it because processing stays on EU infrastructure. That alone ruled out most of the competition.
Converted forty subtitle files one after another. Instant every single time.
Needed one file converted right before a deadline. No signup, no hoops — done in a minute.
No card, no tricks — I tested real files before paying and upgraded a week later because the workflow stuck.
Had trouble with a huge file — support walked me through batch upload the same morning. Rare these days.
SRT (SubRip) is the older, universally supported format; VTT (WebVTT) is the web standard required by HTML5 video players and supports styling and positioning. Timestamps differ slightly — commas in SRT, dots in VTT.
The HTML5 <track> element and most web players (Video.js, JW Player, Plyr) only accept WebVTT. If your captions came as SRT, converting to VTT is the one step between you and working web captions.
Yes — the tool works in both directions. Editors and platforms that prefer SRT get a clean, valid file.
It strips all timestamps and numbering, leaving just the dialogue — handy for scripts, translation quotes and content review.
No — the conversion runs entirely in your browser. Instant, private, offline-friendly.
Completely: no account, no limits, no watermark.
