SRT to VTT Converter
Convert SRT subtitles to WebVTT in your browser. Paste subtitle text or upload an SRT file, preview the VTT output, then copy or download the result.
When to use this converter
Use this tool when you already have an SRT caption file and need a WebVTT file for a web player, publishing workflow, or subtitle test. It keeps the task focused on format conversion, not transcription.
What changes in the file
The converter adds the WebVTT header and changes SRT comma timestamps like 00:00:01,500 into WebVTT dot timestamps like 00:00:01.500. Subtitle text is preserved.

What is the difference between SRT and VTT?
SRT is a common plain subtitle format that uses comma-based milliseconds. VTT is WebVTT, a subtitle format often used for web video and HTML5 video.
Can I use VTT subtitles on YouTube?
YouTube supports several subtitle formats, including WebVTT. Always review the uploaded captions inside YouTube Studio before publishing.
Does this upload my subtitle file?
No. The current converter reads the SRT text in your browser and generates the WebVTT output locally.
Why does my SRT file fail to convert?
The most common reasons are missing timing lines, invalid timestamps, an end time that comes before a start time, or a file that is not actually SRT.
Can I convert VTT back to SRT?
Not in this first version. This page focuses on SRT to VTT conversion so the tool stays small and predictable.
