When converting from SRT to VTT, a few key changes are made to ensure compatibility with the WebVTT specification:
A WEBVTT header line is added at the top of the file, which is required by the VTT format.
Commas in timestamps (00:01:23,456) are replaced with periods (00:01:23.456) to match VTT syntax.
Numeric cue identifiers from SRT are preserved but become optional in VTT. Your subtitle text and timing remain unchanged.
WebVTT (Web Video Text Tracks) is the standard subtitle format for HTML5 video. If you are adding captions to videos on your website using the <track> element, you need VTT files. Most modern video players - including those on platforms like YouTube and Vimeo - also support VTT natively. Unlike SRT, VTT supports advanced features like text positioning, styling with CSS, and chapter markers. Our VTT to SRT converter handles the reverse direction if you need to go back to SubRip format.
No. This tool runs entirely in your browser using JavaScript. Your file is read locally and never sent to any server. The conversion happens on your device, making it completely private.
No. The subtitle text and timing are fully preserved. Only the format-specific syntax changes - the WEBVTT header is added and timestamp commas become periods.
The W3C web standard for the HTML5 <track> element only supports WebVTT. SRT was never adopted as a web standard because it predates the open web video era. You can learn more about adding subtitles with our SRT File Viewer.
Yes. Toggle "Enable editing" above the preview to make the output editable. Any changes you make will be included when you download or copy the file.
The output is saved as UTF-8, which is the required encoding for WebVTT files. If your SRT file uses a different encoding, special characters should still be handled correctly by modern browsers.
