SRT to VTT Converter — Convert SubRip Subtitles to WebVTT Online

The SRT to VTT Converter is a free online tool that converts SubRip (.srt) subtitle files into WebVTT (.vtt) format, which is the modern standard for HTML5 video, web players, and platforms such as YouTube embeds, Vimeo, and many JavaScript-based players. Whether you are a video editor, podcaster preparing transcripts, content creator publishing subtitled videos on your own site, or a developer working with the HTML5 <track> element, this tool delivers a valid VTT file in seconds.

SRT vs VTT — Key Differences

SRT is a simple, widely supported subtitle format that has been around since the early 2000s. WebVTT (Web Video Text Tracks) is a newer W3C standard designed specifically for web video. VTT supports rich formatting (italics, colors, positioning, voice tags, regions), CSS styling, and required-by-browsers compatibility with the HTML5 video track element. To display subtitles on a self-hosted HTML5 video player, you need VTT — SRT will not be recognized. Converting is a one-time step that unlocks modern video accessibility.

How the Conversion Works

The tool reads your SRT file, replaces SubRip timestamps (00:00:00,000) with VTT timestamps (00:00:00.000), adds the required "WEBVTT" header, escapes special HTML characters, and preserves your original subtitle text exactly. Cue numbers, line breaks, and timing are all retained. Upload your .srt file, click Convert, and download the .vtt result immediately.

Why Use Our Tool?

Free, instant, in-browser (your files never leave your device), and mobile-friendly. Use it for accessibility compliance (WCAG, ADA), to add subtitles to self-hosted videos, or to prepare clean transcripts for translation. Bookmark it for any subtitle workflow.
