What is URL Parser?
URL Parser — A URL Parser is a free tool that breaks down any URL into its individual components: protocol, hostname, port, path, query parameters, and fragment.

Break down any URL into its individual components — protocol, hostname, port, pathname, query string parameters, and hash fragment — following the WHATWG URL Standard. Decode percent-encoded query values, inspect UTM campaign tags, debug API endpoints and OAuth callback URLs, and validate redirect chains.
URL Parser: Paste any URL to instantly see it broken down into protocol, host, port, pathname, search parameters, and hash fragment. Each query parameter is displayed as a key-value pair. Useful for debugging redirects and API endpoints.

URL Parser — A URL Parser is a free tool that breaks down any URL into its individual components: protocol, hostname, port, path, query parameters, and fragment.
Paste any full URL (https://example.com/path?key=value#section) or relative URL (/path?query=data) into the parser input field.
Review the parsed URL components: protocol/scheme, hostname, port, pathname, origin, search string, and hash fragment displayed in a structured breakdown.
Inspect each query parameter as a decoded key-value pair in the parameter table — percent-encoded values are automatically decoded to readable text.
Verify UTM tags, API parameters, redirect URLs, or OAuth state values are correctly structured before deployment or campaign launch.
Copy individual components or the full parsed breakdown for use in documentation, bug reports, or team communication.
Debugging broken links, 301/302 redirect chains, and malformed URL structures in web applications
Auditing UTM campaign tracking parameters (utm_source, utm_medium, utm_campaign) for Google Analytics and marketing attribution accuracy
Inspecting OAuth 2.0 callback URLs, authorization code parameters, and state values during authentication flow debugging
Validating API endpoint URL structures, query string formats, and encoded parameter values before production deployment
SEO auditing of canonical URLs, hreflang URLs, and sitemap link structures for crawl consistency
A URL (Uniform Resource Locator) follows a standardized structure defined by RFC 3986 and the WHATWG URL Standard. Every URL consists of up to seven components: scheme/protocol (https, http, ftp), authority containing hostname and optional port (example.com:8080), pathname (/api/v2/users), query string (?page=1&limit=50), and fragment/hash (#section-3). Each component serves a specific purpose in resource identification and navigation. This parser decomposes any URL into these individual parts using the same URL API that modern browsers use internally, ensuring parsing behavior matches real-world browser interpretation.
Query string parsing is particularly valuable because query parameters frequently contain percent-encoded special characters, nested values, array syntax (key[]=value), and multi-level data structures. This tool decodes each parameter value automatically, making it easy to verify UTM campaign tags for marketing attribution, inspect API pagination and filter parameters, validate OAuth redirect URIs and state tokens, audit SEO canonical parameters, and debug tracking pixels from advertising platforms. The visual breakdown eliminates the need to manually parse long URLs in a text editor or write throwaway scripts to extract specific parameter values.
Check scheme (`https`), hostname spelling, path casing, duplicated parameters, and unwanted fragments. Small URL errors can impact crawling, analytics attribution, and user trust.
If values contain encoded symbols (for example `%2F` or `%20`), verify the decoded output and re-encode only the exact parameter value when rebuilding URLs.
Break down a URL into scheme, host, path, query parameters, and hash.
