What is a URL parser?

A tool that breaks a web URL string down into its standard components like protocol, host, path, query parameters, and fragment.

What is percent-encoding in URLs?

A mechanism to encode reserved or non-ASCII characters in URIs using `%` followed by two hexadecimal digits.

What is the query string in a URL?

The portion of a URL that follows a question mark (`?`), containing key-value pairs separated by ampersands (`&`).

What is a URL fragment or anchor?

The portion following a hash mark (`#`) that specifies a location or section on the destination page.

Are query parameters case-sensitive?

Yes. Most web servers and frameworks treat `?ref=abc` and `?REF=abc` as distinct parameters.

Are my URLs sent to ScanSuite servers when parsed?

No. All parsing happens locally in your browser memory.

Why are spaces converted to %20 or + in URLs?

Spaces are unsafe characters in URLs; `%20` is standard percent-encoding, while `+` is used in HTML form submissions.

Can I parse URLs containing non-English characters?

Yes, the parser supports UTF-8 and Internationalized Domain Names (IDN).

What is the difference between URI and URL?

A URL (Uniform Resource Locator) is a specific type of URI that provides the means to act on or obtain a resource by describing its primary access mechanism.

How do I parse a URL inside a query parameter?

The tool automatically percent-decodes query parameter values, revealing any nested URL.

What is the maximum length of a URL?

While RFC 7230 specifies no limit, practical browser limits are around 2,048 characters for compatibility.

Can this tool parse IPv6 host URLs?

Yes, IPv6 addresses inside square brackets (e.g. `http://[::1]:8080`) are fully supported.

What is UTM parameter tracking?

Standardized query parameters used by marketers (e.g., `utm_source`, `utm_medium`) to track traffic sources in analytics.

What is parameter pollution?

A security vulnerability where multiple query parameters with the same key cause unexpected server parsing behavior.

Is this URL parser free to use?

Yes, ScanSuite provides unlimited free URL parsing without registration.

Why does my URL require http:// to parse?

The WHATWG URL standard requires an explicit protocol scheme to establish host vs path context.

How do I copy a single query parameter value?

Click the copy icon next to any row in the extracted query parameter table.

Can I parse local file or mailto URLs?

Yes, scheme handlers like `mailto:`, `file:`, and `ftp:` are supported.

Free Online URL Parser & Query String Analyzer

An online URL parser breaks down Uniform Resource Locators (URLs) into structured structural components — such as scheme, user info, host, port, path, query string parameters, and fragment anchors — decoding percent-encoded characters for rapid API debugging and web development.

Paste any URL into ScanSuite's online URL parser to automatically split its components into scheme, host, port, path, and an interactive key-value table of query parameters with percent-decoded values and one-click copy options.

Uniform Resource Locators (URLs) serve as the fundamental address system of the World Wide Web. Modern web applications, tracking links, OAuth authorization flows, and REST APIs pack complex nested state and parameters into query strings.

ScanSuite's free online URL parser breaks complex web addresses down into clear, structured components. Inspect scheme, host, port, path, query key-value pairs, and fragment anchors instantly in your browser with zero data sent to external servers. Ideal for OAuth debugging, UTM validation, and API endpoint troubleshooting.

ScanSuite's free online URL parser breaks down web addresses into protocol, host, port, path, fragment, and query parameters. With automatic percent-decoding and client-side processing, developers and marketers can inspect links effortlessly.
