A URL Parser is a tool that decomposes a Uniform Resource Locator (URL) into its individual components—such as protocol, hostname, port, path, query parameters, and fragment. This is essential for web developers, SEO specialists, and anyone working with web technologies who needs to inspect, debug, or manipulate URLs programmatically. Our online URL parser uses the browser's native URL API (RFC 3986 compliant) to ensure accurate parsing according to web standards.

A standard URL consists of these key parts:

Scheme / Protocol — e.g., https://, http://, ftp://
Hostname — the domain or IP address (e.g., www.example.com)
Port — optional, specifies the network port (e.g., :8080)
Path — the resource path on the server (e.g., /blog/article)
Query String — key-value parameters after ? (e.g., ?id=123&sort=asc)
Fragment / Hash — anchor after # (e.g., #section2)
Username & Password — optional credentials (rarely used in modern web)

Hostname is the domain name or IP address alone (e.g., www.example.com or 192.168.1.1). Host includes the hostname plus the port number if one is explicitly specified (e.g., www.example.com:8080). If no port is specified in the URL, the host and hostname are identical. This distinction is important when working with non-standard ports in web development and API configurations.

Query parameters are the key-value pairs that appear after the ? character in a URL. They are separated by & and follow the format key=value. Our tool uses the URLSearchParams API to parse them accurately, automatically handling URL encoding (e.g., %20 → space, %2F → /). Each parameter is displayed with both its raw encoded form and its decoded, human-readable value. This is particularly useful for debugging tracking parameters, API calls, and form submissions.

The fragment identifier (also called the hash) is the part of the URL after the # symbol. It is never sent to the server — it is handled entirely by the browser (client-side). Common uses include: navigating to a specific section of a page via anchor links (e.g., #faq-section), tracking state in single-page applications (SPA routing with #/dashboard), and storing temporary client-side data. Understanding fragments is crucial for front-end developers working with SPAs and anchor navigation.

If the port in your URL matches the default port for the protocol (e.g., port 80 for HTTP or port 443 for HTTPS), the URL API may return an empty string for the port property. This is because default ports are implicit and typically omitted in canonical URL representations. For example, https://example.com:443/path will show an empty port since 443 is the default for HTTPS. Only non-standard ports (like 8080, 3000, 8443) will appear explicitly in the parsed output.

Yes. Modern browsers automatically convert internationalized domain names (containing non-ASCII characters like Chinese, Arabic, or Cyrillic) into Punycode encoding via the URL API. For example, a domain like 例.com will be parsed as its Punycode equivalent xn--fsq.com. Our tool displays the hostname exactly as the browser interprets it, which is the form actually used in DNS resolution and HTTP requests.
