URL Parser

The URL Parser breaks a web address into the pieces that browsers, servers, crawlers, analytics tools, and API clients actually use: protocol, credentials, host, port, path, query string, individual query parameters, and fragment. Paste a full URL such as https://example.com:8443/docs?q=url#parts, a host-only value such as example.com/path, or a relative URL such as /search?q=tools to inspect its structure.

How to Use

1. Paste the URL. Enter one absolute, protocol-relative, host-only, or relative URL in the input field.
2. Check the live anatomy. Use the visual rail to confirm the protocol, host, port, path, query, and fragment before parsing.
3. Click Parse URL. Submit the URL to generate a complete component breakdown with decoded values.
4. Review query parameters. Inspect each query key and value, including repeated keys and empty values.
5. Copy the part you need. Use the copy buttons next to individual components or the rebuilt URL.

Useful Checks for Developers and SEO

URL structure affects routing, cache keys, canonical links, redirects, tracking parameters, crawl consistency, and API debugging. This parser highlights repeated query keys, custom ports, percent-encoded values, credentials in URLs, and fragments that are not sent to the server. Those details are easy to miss when a URL is long or copied from logs.

FAQ

What does a URL parser show?

A URL parser separates a URL into its scheme or protocol, optional credentials, host, port, path, query string, query parameters, and fragment. This makes it easier to debug routing, analytics tags, API endpoints, redirects, and encoded values.

Why is host different from origin?

The host is only the domain name or IP address. The origin combines the protocol, host, and port, so https://example.com and http://example.com are different origins even though they use the same host.

Are URL fragments sent to the server?

No. The fragment after the # symbol is handled by the browser and is not sent in the HTTP request line. Servers usually see the protocol, host, path, and query string, but not the fragment.

How are duplicate query parameters handled?

This parser preserves duplicate query keys in order and highlights repeated keys. Many web frameworks expose repeated keys as arrays or lists, while some applications keep only the first or last value.

What does percent decoding mean?

Percent decoding converts encoded octets such as %20 back into readable characters such as spaces. The parser shows decoded path and query values while preserving the raw URL text for comparison.

Is it safe to include passwords in URLs?

No. Credentials inside URLs can appear in logs, browser history, screenshots, analytics tools, and referrer data. Use headers, cookies, or secure authentication flows instead of embedding passwords in URLs.
