URL Validator
Enter a full URL (with http:// or https://) and see whether it's valid.
How it works
This validator uses the browser's native URL parser (the same WHATWG URL Standard used internally by links, forms, and the browser's own address bar), instead of a custom regular expression — URLs have a syntax full of edge cases (ports, user/password, bracketed IPv6, percent-encoding) that a dedicated parser handles correctly. After confirming the text is a well-formed URL, the tool still requires the protocol to be http or https — other protocols (ftp:, mailto:, javascript:, etc.) are technically valid URLs, but out of scope for this validator.
