About SRT to VTT Converter Tool
Published: Last Updated:
This SRT to VTT Converter transforms SubRip (.srt) subtitle files into WebVTT (.vtt) format — the HTML5 video standard for <track> captions. The conversion replaces the SRT comma timestamp separator with a period (00:00:00,000 → 00:00:00.000) and adds the WEBVTT header. Conversion happens entirely in your browser — your subtitle file is never uploaded to any server.
Key Features
- Converts SRT timestamp format to VTT format (comma → period).
- Adds required WEBVTT file header.
- Supports any SRT file with or without styling tags.
- Download result as .vtt file.
- Runs entirely in your browser.
How to Use the Tool
- Paste your SRT content into the input field, or upload an .srt file.
- The VTT-formatted output appears instantly.
- Copy the result or download it as a .vtt file.
Core Benefits
- VTT is the native subtitle format for HTML5 <video> elements.
- Required for video hosting platforms that support captions (Vimeo, JW Player, Video.js).
- VTT supports additional features like positioning and styling that SRT does not.
Common Use Cases
- Converting subtitles from a video editor (exports SRT) to VTT for web embedding.
- Preparing captions for a course video on a platform requiring VTT.
- Converting subtitles for use with the HTML5 <track> element.
Pro Tips
- SRT and VTT are structurally almost identical — the main difference is the timestamp separator (comma vs period) and the WEBVTT header.
- VTT supports cue settings for positioning text (e.g. line:80% position:50%) which SRT does not.
