How to Convert SRT to VTT Online (Free & Easy)
Need to convert an SRT subtitle file to VTT format? Whether you're uploading captions to a website, working with an HTML5 video player, or preparing subtitles for Vimeo, converting SRT to VTT takes seconds — and you don't need to install any software.
In this guide, we'll explain why the conversion is needed and show you how to do it instantly for free.
Why Convert SRT to VTT?
SRT (SubRip Text) and VTT (WebVTT) are both plain text subtitle formats, but they're used in different contexts:
- SRT is the universal standard — used by video editors, YouTube, and most media players
- VTT is the web standard — required by HTML5 video players, Vimeo, and many e-learning platforms
If you've received an SRT file but need VTT for your website or platform, you need to convert it. The difference is small but important — VTT requires a WEBVTT header and uses a dot instead of a comma in timestamps.

What Changes During Conversion?
The actual subtitle text stays identical. Here's what changes technically:
| Element | SRT | VTT |
|---|---|---|
| File header | None | WEBVTT added |
| Timestamp format | 00:00:01,000 | 00:00:01.000 |
| File extension | .srt | .vtt |
Where Is VTT Used?
After converting, your VTT file will work with:
- HTML5 video — use the
<track>element to add subtitles to any web video - Vimeo — Vimeo requires VTT format for caption uploads
- E-learning platforms — tools like Teachable, Thinkific, and Moodle use VTT
- Video.js — popular open-source web video player
- JW Player — widely used commercial video player
Can I Convert Multiple SRT Files at Once?
Our current converter handles one file at a time. If you have multiple files to convert, simply repeat the process for each one — it only takes seconds per file.
