How this service works
SubRip to WebVTT. POST an .srt file; the response is a .vtt file — a WEBVTT header and timestamps written with a decimal point instead of a comma. Cue numbers are kept as WebVTT cue identifiers and caption text is passed through untouched, so a comma inside a line of dialogue is not mistaken for a timestamp separator.
Output
A plain-text WebVTT file beginning with the WEBVTT header, with all timestamp separators changed from commas to decimal points. Cue numbers are preserved as WebVTT cue identifiers, and caption text lines are passed through unchanged. Content-type is text/vtt.
Example use cases
HTML5 video player subtitle prep
“I've got an SRT subtitle file from my video editor but the HTML5 video player on my website only accepts WebVTT — can you convert it to VTT format for me?”
Streaming platform caption upload
“My streaming platform requires WebVTT captions but my transcription service only exports SRT files. Can you convert this SRT to a proper VTT file with the timestamps fixed?”
Automated subtitle pipeline conversion
“For every SRT file my production team exports, I need it automatically converted to WebVTT so our web CMS can ingest it — can you run this SRT through the SRT-to-VTT converter?”
