About this tool

URL Validator is a static, client-side tool with no backend. URL Validator builds and encodes links in your browser, percent-encoding parameters so the URL stays valid.

Reserved characters are escaped to standard rules so the link works everywhere. It behaves the same on desktop and mobile, with nothing stored remotely.
