URL Validator
Paste a URL to check whether it is valid — complete with the reason if it is invalid and a component breakdown if it is valid. Everything is processed on your device.
Everything runs in your browser. Your data is never sent to our servers.

About URL Validator
URL Validator uses the browser's built-in WHATWG URL API to check whether a string is a valid absolute URL, then breaks it into protocol, host, path, query, and fragment. Non-web schemes (e.g. ftp:, mailto:) are flagged as a warning, not an error.
Because it uses the same parser as the browser, the result is consistent with how links are actually processed.
FAQ
Is my data sent to a server?
No. All validation runs in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
How is this validator different from a parser or formatter?
A validator answers one question: is this input correct/valid? It returns a valid/invalid badge with the reason. A parser breaks input into its components, and a formatter tidies its layout. Use a validator when you just need to confirm something is sound before using it.
