URL Validator
Validate URL syntax and inspect parts.
This free URL validator goes beyond a format check. For each address it parses the URL with the browser's own engine, breaks it into protocol, host, port, path, query and fragment, then runs a series of safety and quality checks: it flags insecure http, non-web schemes, embedded credentials, non-standard ports,IP-address and localhost hosts, internationalised (punycode) domains and known URL shorteners. A bare domain likeexample.org is auto-normalised to https://.
With DNS checking on, both the TLD (is.com / .dev a real top-level domain?) and thefull host are looked up live over secure DNS-over-HTTPS A made-up TLD or a host that doesn't resolve is marked invalid. Known URL shorteners (bit.ly, t.co…) are expanded to show their real destination. Paste a whole list to validate in bulk.
