Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Convert WebVTT captions to SRT entirely in your browser — the classic format practically every desktop player, TV and set-top box accepts. Drop the .vtt files, download the .srt twins. Nothing is uploaded anywhere.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
When SRT is the right target
VTT rules the web, but the living room still speaks SRT: VLC, TVs, media servers and older players all expect it. The conversion re-numbers the cues, turns dot-milliseconds into commas and drops web-only cue settings like position and alignment — the text and timing carry over exactly.
Web-only markup is cleaned out
VTT allows voice spans, class tags and karaoke timestamps inside the text; SRT players would show those as literal angle-bracket noise. They are stripped on the way through, while <i>, <b> and <u> — which SRT understands — stay. NOTE and STYLE blocks disappear with them. The reverse trip is SRT to VTT.
Frequently asked questions
Do positions and colors carry over?
No — SRT has no standard way to express them, so cue settings and styling tags are removed. The words and timing, the part that matters, stay exact.
Will the file work on my TV?
That is the point of SRT: it is the most widely accepted subtitle format there is. Name it after the video file and most players pick it up automatically.
Can I fix out-of-order cues?
Cues are sorted by start time during conversion, so a track stitched from fragments comes out in playable order.
Is anything uploaded?
No. The conversion is plain text processing that runs entirely in your browser — the server only delivers this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
