ມັນເຮັດວຽກແນວໃດ

Different players and platforms want different subtitle formats — YouTube uses SBV, the web uses WebVTT, most video files use SRT. This converts between them while keeping the timing intact.

1
You paste or drop a subtitle file
SRT, VTT, SBV, LRC, or ASS/SSA. The input format is detected automatically — nothing is uploaded.
2
Cues are parsed into a common model
Each caption's start time, end time, and text are extracted, normalising the different timecode styles (commas, dots, centiseconds).
3
It's re-serialised to your target format
The cues are written out in the format you choose, with correct timecodes and structure for that format.
4
Copy or download
Grab the converted captions with the right file extension.

Captions can contain unreleased dialogue or sensitive transcripts. Everything is parsed and converted on your device — your subtitles never leave the browser.
