URL Parser

A URL parser breaks down a URL into its components: scheme, host, path, query, and fragment. It extracts scheme, host, subdomain, domain, TLD, path, directory, filename, and file extension. The tool is useful for understanding URL structure, debugging, SEO analysis, and development.

What is URL Parser?

The URL Parser is a free online tool that parses any URL and returns its components in a structured format. You paste or type a URL, and the tool extracts: scheme (e.g., https), protocol (same as scheme), authority (host), host, hostname, subdomain (if present), domain (without subdomain), TLD (top-level domain), resource (path), directory (path without filename), path, file name (basename of path), and file suffix (extension). For URLs with query strings like https://google.com/?utm_source=google&utm_medium=social, the tool parses the base URL. The output is displayed in a table for easy reference. The tool is useful for developers, SEO professionals, and anyone who needs to understand URL structure.

Understanding URL structure is essential for many tasks. When building web scrapers, you need to extract the domain to respect robots.txt. When analyzing campaign URLs, you need to see the path and query parameters. When debugging routing issues, you need to verify how the URL is being parsed. The URL Parser provides an instant breakdown of any URL you provide. It uses PHP's parse_url and pathinfo functions to extract components reliably. The subdomain is automatically detected when the host has more than two parts (e.g., www.example.com has subdomain www). The TLD is the last part of the domain. The directory and file name are derived from the path component.

URLs with query strings (e.g., ?utm_source=google&utm_medium=cpc) are common in marketing. The tool parses the base URL. The query string is part of the URL but not broken into individual parameters in the tool's output. For full query parameter parsing, you would need to parse the query string separately. The tool focuses on the structural components: scheme, host, path, and their sub-parts. Use the output to understand how your application or framework will interpret the URL. For SEO analysis, the path and domain are often the most important. For security analysis, the scheme and host matter. For routing, the full path is key. The tool is a quick reference for URL anatomy.

PHP's parse_url function is the backbone of the tool. It parses URLs according to RFC 3986. The tool extracts scheme, host, port, path, query, and fragment. The pathinfo function breaks down the path into directory and filename. The subdomain logic checks if the host has more than two parts (e.g., www.example.com has www, example, com). For example.com, there is no subdomain. For mail.example.com, mail is the subdomain. The domain is the rest. The TLD is the last part. For some domains (e.g., co.uk), the TLD logic may be simplified. The tool provides a practical breakdown for most URLs. Use it for quick debugging, documentation, or integration with your own scripts. The output is displayed in a table for easy reading. Copy any value as needed.

Who Benefits from This Tool

Web developers and DevOps engineers use it to debug URLs and understand routing. SEO professionals analyze URL structure for optimization. Digital marketers parse campaign URLs to verify UTM parameters. Data analysts extract domain and path information from URL lists. Security researchers analyze URLs for phishing or malicious patterns. Anyone who works with URLs can benefit from quick parsing.

Key Features

Scheme and Protocol

Extracts the scheme (http, https, ftp, etc.) from the URL. Used for protocol-relative URLs and security.

The scheme determines how the resource is accessed. HTTPS indicates encrypted connections. HTTP is unencrypted. The tool extracts this for reference. Many applications need to know the scheme when constructing absolute URLs or when enforcing HTTPS. The protocol field is an alias for scheme in this tool. Both contain the same value. When building redirects or canonical URLs, the scheme is important for consistency.

Host and Authority

Extracts the full host (domain and optional port). Authority is the same as host in this context.

Subdomain and Domain

For hosts like www.example.com, subdomain is www and domain is example.com. For example.com, subdomain is null and domain is example.com.

TLD Extraction

Extracts the top-level domain (e.g., com, org, net) from the host.

Path Components

Resource is the full path. Directory is the path without the filename. Path is the full path. File name is the basename. File suffix is the extension (e.g., php, html).

For a URL like https://example.com/blog/2024/post.php, the path is /blog/2024/post.php, the directory is /blog/2024, the file name is post.php, and the file suffix is php. The resource is the same as path. These components are useful when building routing logic, generating sitemaps, or analyzing URL structure. The tool uses PHP's pathinfo to extract the directory and filename from the path.

Query String Support

The tool accepts URLs with query strings. The path and query are parsed separately. Query parameters can be analyzed for UTM and other tracking parameters.

How to Use

1. Paste or type a URL into the input field.
2. Complete the captcha if required.
3. Click the Start or Parse button.
4. Review the parsed components in the table.
5. Use the output for debugging, analysis, or documentation.

Common Use Cases

• Debugging URL structure and routing
• Extracting domain from URL lists
• Analyzing UTM and tracking parameters
• Understanding SEO URL structure
• Parsing URLs for data pipelines
• Checking subdomain and path structure
• Documenting URL structure for APIs
• Validating URL format before processing

Tips & Best Practices

Use the tool to verify URLs before processing in scripts. For UTM analysis, combine with a query string parser if you need individual parameters. The subdomain is extracted when the host has more than two parts (e.g., www.example.com). For internationalized domains, the tool uses standard parsing.

Limitations & Notes

The tool uses PHP's parse_url and pathinfo. Complex or malformed URLs may produce unexpected results. Query parameters are not broken into key-value pairs in the output; they are part of the URL. The tool does not validate that the URL is reachable or that the domain exists.
