How to convert SRT to VTT online

Frequently asked questions
What is the difference between SRT and WebVTT?
Both store timed text. WebVTT starts with a WEBVTT header and uses periods before milliseconds. SRT normally uses numbered blocks and commas. Choose the format your destination asks for.
Can I use the converted VTT file in an HTML video?
Yes. An HTML track element can reference a WebVTT file alongside your video. Upload the exported file to your own hosting and configure the track there; this converter does not publish the video or subtitles for you.
Does this add subtitles permanently to the picture?
No. The output is a separate text track that a player can show or hide. Rendering captions into the picture requires a video editor or a dedicated caption-burning tool.
Will the converter keep SRT styling?
Words and cue times are retained, while styling and positioning are removed with a note. Keep your original if you need to reproduce its presentation in another editor.
