The format is the easy part.
WebVTT is the timed-text format used by HTML video tracks. This converter adds the WEBVTT header and changes SRT’s comma-based millisecond separator to a period. It preserves the cue text and timing so you can move an existing caption file into a compatible web player without uploading your video.
How it works
- Paste your SRT captions or choose an .srt file smaller than 500 KB.
- Leave VTT selected, then convert and inspect the WEBVTT output.
- Download the .vtt file and test it with your destination player.
A few things to know
This converts an existing timed caption file; it does not generate subtitles from plain text or audio. Styling, cue settings, comments, and positioning metadata are removed. A format conversion does not correct wording or synchronize mistimed captions.
Common questions
Is changing the filename enough?
No. WebVTT uses a header and different timestamp syntax. Convert the contents before saving the file with a .vtt extension.
Will this make captions appear on my website?
It creates a VTT file. Your web player must still load that file as a caption track. Test it in the player before publishing.
