Why convert SRT to VTT?

The HTML5 <track> element only accepts WebVTT. Converting rewrites the timestamp format and adds the WEBVTT header so your captions actually appear in the browser player.

How it works

Drop your SRT file above and Morphix decodes it locally, then re-encodes it as VTT using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
