Breaking down a URL: parts, an example and common problems
A web address has several parts, each with a job. Paste a full URL and the tool splits it into protocol, host, port, path, query parameters and hash using the browser's built-in URL parser, so nothing is sent anywhere.
Example. Parsing https://shop.example.com:8443/products/shoes?color=red&size=10&utm_source=news#reviews returns:
| Part | Value |
|---|---|
| Protocol | https |
| Domain (host) | shop.example.com |
| Port | 8443 |
| Route | /products/shoes |
| Parameters | color = red, size = 10, utm_source = news |
| Anchor (hash) | reviews |
Things to know
- The port shows "-" when the URL uses the default for its protocol (443 for https, 80 for http).
- Parameter values are shown decoded, so
%20appears as a space. - The hash is handled in the browser and is never sent to the server, which is why analytics tools do not see it.
Common mistakes
- Missing the scheme.
example.com/pageis reported as invalid; start withhttps://. - Spaces or unusual characters in the address; encode them first with the URL encoder.
- Repeated parameters (such as
tag=a&tag=b) show as separate entries; check which one your application reads.
Handy for debugging redirects, checking tracking links built with the UTM builder or cleaning up titles with the slug generator.

Why does the port show a dash?
The URL does not specify one, or it uses the default port for its protocol (80 for http, 443 for https). The browser treats the default as implied.
Is the part after # sent to the website?
No. The fragment stays in your browser and is used for in-page navigation, so servers and server logs generally never see it.
