What does SRT to VTT do?
Convert existing SRT captions to WebVTT without transcribing audio again. SceneDub keeps basic cue text and timing, adds the WEBVTT header, and formats millisecond separators for VTT. Conversion runs in your browser; review styling in the destination player.

Frequently asked questions
What changes when SRT is converted to VTT?
The converter adds the WEBVTT header and changes timestamp milliseconds from a comma to a period while preserving cue timing and text.
Does SceneDub upload my SRT file?
No. This converter reads and transforms the subtitle text locally in your browser.
Can I download the converted VTT file?
Yes. You can copy the generated WebVTT text or download it as a .vtt file.
Will subtitle styling be preserved?
Basic cue text is preserved. Format-specific positioning, comments, regions, and advanced styling should be reviewed after conversion.
