What's actually different between SRT and WebVTT?

They're similar in concept, but WebVTT uses a different header, timestamp format and file structure — a file in one format generally won't be recognized by a player expecting the other.

Which format should I use for web video players?

WebVTT is the standard for HTML5 video players on the web, while SRT is more commonly used in general video editing and playback software.

Does converting between formats lose any subtitle data?

No, the core timing and text content carry over completely — only the file structure and syntax change.

Does SRT ↔ VTT Converter upload my files to a server?

No. SRT ↔ VTT Converter runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

SRT and WebVTT are the two most common subtitle formats, but they're not always interchangeable — different platforms and video players expect one specifically, and the syntax differs enough that a file in the wrong format won't load correctly. This tool converts subtitle files between SRT and WebVTT in either direction, matching whichever format your specific platform or player actually requires.
