What changes when SRT is converted to VTT?

Cue numbers are removed, comma-separated milliseconds become dots, and the required WEBVTT header is added. Cue timings, line breaks and caption text stay intact.

Can I use the VTT file for HTML5 video?

Yes. WebVTT is the subtitle format used by HTML video track elements and is also accepted by many video platforms and editors.

No. Conversion and download happen locally in your browser, so the source subtitle file is never sent to Clip Caption Kit.

SRT and WebVTT format differences

SRT uses numbered cues and comma-separated milliseconds. WebVTT starts with aWEBVTT header, uses dots in timestamps and does not require cue numbers. This converter changes that structure without rewriting the caption text.

SRT: 00:00:01,000 --> 00:00:02,500
VTT: 00:00:01.000 --> 00:00:02.500
