SRT to VTT Converter

Prepare Your Subtitles for HTML5 with SRT to VTT

While SubRip (.srt) is the industry standard for desktop video players and editing software, modern web browsers require a different format. To display captions on the web using the HTML5 <track> element, you must use WebVTT (.vtt).

Our SRT to VTT Converter automates this technical transformation. It parses your existing subtitle files, inserts the required WEBVTT header, and standardizes the timestamp formatting (swapping commas for dots). This ensures your closed captions load correctly in VideoJS, Plyr, and native HTML5 video players without error.

Why Convert SRT to VTT?

• Native Browser Support: VTT is the only format fully supported by the HTML5 standard for video tracks.
• Advanced Styling: Unlike SRT, WebVTT allows for CSS styling, cue positioning, and alignment control.
• Privacy & Speed: This tool runs 100% in your browser. Your subtitle data is processed instantly via JavaScript and never uploaded to a server.

Frequently Asked Questions

How do I convert SRT to VTT subtitle format?

Simply paste your raw SRT text into the input box above and click "Convert." The tool will automatically restructure the file, adding the mandatory headers and fixing the timecodes for web compatibility.

What is the difference between SRT and VTT files?

Technically, SRT uses commas for milliseconds (00:00:00,000) and strictly uses numbered sequences. WebVTT uses dots for milliseconds (00:00.000), requires a "WEBVTT" header at the start, and makes line numbers optional.

Can I use VTT files for HTML5 video players?

Yes. WebVTT is the standard. To use it, you reference the file in your HTML like this: <track label="English" kind="subtitles" src="subtitles.vtt" srclang="en">.

How do I convert SubRip subtitles to WebVTT?

Manual conversion involves three steps: 1) Add "WEBVTT" to the first line. 2) Replace all timestamp commas with periods. 3) (Optional) Remove the cue numbers. Our tool performs all three steps instantly.

Which subtitle format is better for web videos SRT or VTT?

VTT is superior for the web. It is the W3C standard for HTML5 video and offers advanced features like cue settings (align:start line:0%) that SRT does not support.
