No. Conversion is handled entirely in Javascript inside your browser memory. Your text content is never sent over the internet, keeping private notes or documents secure.

A URL Slug replaces spaces with hyphens, removes special characters, and lowercase everything to make text clean and compatible with browser address URLs.
