Why do I need to include the protocol (https://) for this to work?

The browser's URL parser this tool relies on requires a complete, absolute URL to parse correctly — without a protocol, a string like "example.com/page" is ambiguous (it could be a relative path rather than a full URL), so the parser can't reliably determine its structure.

What's the difference between 'Host' and 'Hostname'?

Hostname is just the server address (like `example.com`). Host includes the port number too, if one is explicitly specified in the URL (like `example.com:8080`) — for URLs using the default port for their protocol, Host and Hostname will look identical.

What does the '(default)' port mean?

It means no port was explicitly specified in the URL, so the browser uses the protocol's standard default — port 443 for HTTPS or port 80 for HTTP — without it needing to appear in the URL itself.

Can this parse relative URLs, like "/page?id=5"?

No — this tool requires a complete, absolute URL with a protocol and host. Relative URLs only make sense in the context of a base URL they're relative to, which this standalone tool doesn't have.

Does this decode percent-encoded characters in the query parameters?

Yes — query parameter values are automatically decoded from their percent-encoded form, so a value like `hello%20world` in the raw URL is shown as "hello world" in the parsed parameter list.

About Extract Domain From URL

A URL is a compact string that actually encodes several distinct pieces of information: which protocol to use, which server to connect to, which specific resource on that server to request, and any additional parameters or page-section reference — all packed together in a format most people read as a single opaque blob rather than a structured piece of data. A URL parser breaks that string apart into its named components, making each piece individually visible and usable.

This tool uses the browser's built-in, standards-compliant URL parser (the same one used internally by `fetch()`, `window.location`, and every other URL-handling API in JavaScript) to break a URL into its protocol (like `https:`), host and hostname (the server address, with and without the port), port (explicit or the protocol's default), pathname (the specific resource path being requested), and hash (the fragment identifier after a `#`, often used for in-page navigation or, in older single-page apps, for client-side routing).

Query parameters get special treatment: rather than showing the raw query string as one block of text, this tool parses it into individual key-value pairs, making it immediately clear what parameters a URL is actually passing and what their values are — genuinely useful for understanding a long, parameter-heavy URL (like one with UTM tracking parameters, a search query, pagination, and filters all combined) at a glance, rather than manually splitting the query string by `&` and `=` yourself.

This is useful across a range of everyday development and debugging tasks: understanding exactly what a long, unfamiliar URL from a log file or bug report is actually requesting, checking whether tracking or campaign parameters are present and what they say, verifying a redirect URL's structure before using it in code, or just satisfying curiosity about a particularly long or cryptic-looking URL you've encountered.

How it works

Paste a full URL. Enter any complete URL, including its protocol (https://).
See it broken down. Protocol, host, port, path, and hash are shown as separate, labeled fields.
Review query parameters. Every query parameter is listed individually as a key and value.
