Frequently Asked Questions

What is the difference between SRT and VTT?
Both are plain-text subtitle formats. SubRip (.srt) is an older, widely-supported format used by most video players and editing software — it uses a comma (,) as the millisecond separator and sequential cue numbers. WebVTT (.vtt) is a web standard designed for HTML5 <video> elements — it uses a period (.) as the millisecond separator and starts with the WEBVTT header. When you convert SRT to VTT, this tool handles the timestamp format and header differences automatically.
Will the conversion change my subtitle text?
No. Only the container format changes — the timestamp representation is converted from SRT syntax to VTT syntax, and a WEBVTT header is added. All subtitle text, line breaks, and cue ordering are preserved exactly as they appear in the original file.
Does this tool upload my file to a server?
No. The entire conversion happens locally in your browser using JavaScript. Your file never leaves your device, which makes it completely private and available offline.
Why would I need to convert SRT to VTT?
WebVTT is the native subtitle format for HTML5 video. If you are embedding subtitles in a web page using the <track> element, or uploading to platforms like YouTube or Vimeo that prefer VTT, you need to convert from SRT. VTT also supports advanced features like positioning and styling if needed later.
Can I convert VTT back to SRT?
This tool only converts SRT to VTT. If you need to go in the other direction, use our VTT to SRT converter tool.
