About
Checks the format, protocol and structure of a URL. Useful for verifying links before publishing.
How to validate a URL correctly
The URL validator checks the structure of a web address, verifying protocol, domain, and the formation of path, port, query, and fragment. It is essential for catching malformed links before publishing or sending them.
A URL is made of several parts: protocol (http/https), domain (example.com), path (/folder/file), query string (?a=1), and fragment (#section). The tool checks that these parts are in the right order and use valid characters.
Validation is useful when reviewing links in emails, spreadsheets, code, and forms, where a stray space or an invalid character can break the whole link.
It is important to understand that validating the structure does not test whether the page is online. A URL can be perfectly formed and still return a 404, or point to a nonexistent domain.
Examples
- https://example.com/contact → valid.
- htp://example.com or example .com/route → invalid (wrong protocol or space in the domain).
Limitations
- Validation is structural: it does not check whether the link is online, whether the domain exists, or whether the content is safe.
- URLs with internationalized domains (IDN/punycode) may be handled conservatively.

Frequently asked questions
Does a valid URL always work?
No. Validation checks the structure. The link may be offline or point to a nonexistent page even if structurally valid.
Does the URL need to start with http or https?
Yes, to be considered a complete web URL. Links without a protocol (example.com/route) are accepted as relative references in some contexts, but validation recommends the protocol.
Are spaces allowed in a URL?
No. Spaces must be encoded as %20. A literal space usually indicates a malformed link.
