SRT to VTT
Paste the contents of an SRT (SubRip) subtitle file and convert it to WebVTT (Web Video Text Tracks) format. WebVTT is the standard subtitle format for HTML5 video players and is required by most modern web video platforms. The conversion adds the required WEBVTT header and adjusts timestamp formatting from SRT's comma-separated milliseconds to WebVTT's dot-separated milliseconds.
This is a pure text transformation — no video processing or ffmpeg required. The conversion is instant and handles the format differences automatically: adding the WEBVTT header, converting timestamp separators (commas to dots), and preserving all subtitle text and timing.
Useful for web developers adding subtitles to HTML5 video, content creators preparing files for platforms that require VTT, or anyone migrating subtitle files between formats.

Frequently asked questions
What's the difference between SRT and VTT?▼
SRT (SubRip) is the most common subtitle format, widely used in media players and video editing software. VTT (WebVTT) is the web standard, required by HTML5 video. The main differences are: VTT has a WEBVTT header, uses dots instead of commas in timestamps (00:01:23.456 vs 00:01:23,456), and supports additional styling features like CSS.
Does this preserve styling or formatting?▼
Basic text and timing are fully preserved. SRT supports limited formatting (bold, italic via HTML tags) which is carried over as-is. WebVTT supports additional styling features (CSS, positioning) that aren't present in SRT, so those won't be added automatically.
Can I convert a large subtitle file?▼
Yes. The conversion is a simple text transformation that runs instantly in your browser regardless of file size. Even a feature-length film's worth of subtitles (thousands of lines) converts in milliseconds.
