SRT to VTT
Convert Subtitle Files from SRT to VVT
What Is an SRT to VTT Converter?
An SRT to VTT Converter is a free tool that transforms subtitle files in the SubRip (.srt) format into the WebVTT (.vtt) format required for HTML5 web video players. If you have a set of SRT captions and need to display them on a web page using the HTML5 <track> element, or upload them to a platform that requires WebVTT format, our free DaniProTools SRT to VTT Converter performs the conversion accurately and instantly without any software installation.
SRT is the most common subtitle format in offline video playback and video editing workflows. WebVTT is the standard for web-based video captioning. Both formats store the same timed text content but use slightly different syntax — our converter bridges the gap automatically and reliably.
How to Convert SRT to VTT

- Click the 'Convert to VTT' button
- Review the WebVTT output in the preview panel
- Click 'Download VTT' to save the converted .vtt file to your device

How to Use VTT Files in an HTML5 Video Player
Once you have converted your SRT file to VTT format, you can add it to any HTML5 video element on your website using the <track> tag:
<video controls>
<source src="your-video.mp4" type="video/mp4">
<track src="subtitles.vtt" kind="subtitles" srclang="en" label="English">
</video>
The kind attribute can be set to subtitles, captions, descriptions, chapters, or metadata depending on the type of timed text you are adding.

Q: Is the SRT to VTT converter free?
A: Yes, completely free. Convert SRT subtitle files to VTT format instantly with no account or login required.
Q: Does the converter change any subtitle text or timing?
A: No. The SRT to VTT conversion only updates the file header, timestamp format, and blank line structure. All subtitle text content and timing values are preserved perfectly.
Q: Can I add the VTT file to a YouTube video?
A: YouTube accepts both SRT and VTT subtitle formats for upload. If your captions are already in SRT format, you can upload them directly to YouTube without conversion. Convert to VTT only when the specific platform or video player you are using requires it.
Q: What is the difference between subtitles and captions?
A: Subtitles are transcriptions or translations of spoken dialogue — intended for viewers who can hear but do not understand the language. Captions include all audio content, including sound effects and speaker identification — intended for viewers who are deaf or hard of hearing. Both are stored in the same SRT and VTT file formats.
