Parse URLs into components and decode query parameters.
The URL Parser is a free, browser-based tool that breaks any URL into its individual components — protocol, hostname, port, pathname, query string, and hash fragment — and displays them in a clear, structured format. It also decodes URL-encoded query parameters so you can read their actual values at a glance. This is an essential tool for web developers, QA engineers, and anyone who works with links and web addresses regularly.
A URL (Uniform Resource Locator) is a structured string that identifies a resource on the web. While a URL looks like a single piece of text, it is actually composed of several distinct parts, each with a specific role. The protocol (http or https) defines how the resource is accessed. The hostname identifies the server. The port specifies which network port to use. The pathname points to a specific resource on the server. The query string passes parameters to the server or application. The hash fragment identifies a specific section within the page.
Parsing a URL manually is tedious and error-prone, especially when query strings contain URL-encoded characters like %20 for spaces or %2F for slashes. This tool uses the browser's built-in URL API to parse the input accurately and then presents each component in a labeled table, with query parameters decoded and displayed in a separate section showing both the raw encoded value and the decoded human-readable value.
The tool is useful for debugging, analysis, and learning. Developers use it to inspect URLs from API responses, verify redirect targets, or understand how query parameters are structured in a third-party service. QA engineers use it to validate that links in a web application are correctly formed. Anyone can use it to understand what a complex URL actually means.
URLs must include the protocol (http:// or https://) to be parsed correctly. If you paste a URL without the protocol, the parser will report an invalid URL. Always include the full URL starting with the scheme when using this tool.
The decoded value column in the query parameters table is especially useful when working with URLs that contain encoded spaces (%20), encoded slashes (%2F), or encoded special characters. The raw value shows exactly what is in the URL string, while the decoded value shows what the server or application will actually receive after decoding.
If a URL contains a port number (e.g., https://example.com:8080/path), the port is shown separately from the hostname. If no port is specified, the tool shows "(default)" to indicate that the standard port for the protocol is being used — port 80 for HTTP and port 443 for HTTPS.
While developers can parse URLs in a browser console using new URL(string), this tool presents the results in a structured, readable format without requiring any coding knowledge. The query parameter table with decoded values is particularly valuable — it saves the step of manually decoding percent-encoded strings and makes it easy to scan all parameters at once.
The tool is also useful for non-technical users who need to understand or verify a URL they received in an email, a document, or a web application. Being able to see each component labeled clearly removes the ambiguity of reading a long, complex URL as a single string.
Your privacy is our priority. All processing happens entirely in your browser using JavaScript. No files, data, or inputs are ever uploaded to any server. Everything stays on your device, making this tool completely safe to use with sensitive content.
The parser breaks a URL into: protocol (https://), hostname (example.com), port (:8080 if present), pathname (/path/to/page), query string (?key=value pairs), and fragment (#section). Each component is displayed separately for easy inspection.
URL encoding (percent-encoding) replaces characters that are not allowed in URLs with a % followed by their hex code. Spaces become %20, & becomes %26, etc. This is needed when including special characters in query parameters or path segments.
The query string (?key=value) is sent to the server as part of the request. The fragment (#section) is processed only by the browser and is never sent to the server. Fragments are used for in-page navigation and single-page app routing.
Start with the base URL, add ? before the first parameter, then key=value pairs separated by &. For example: https://example.com/search?q=hello+world&page=2&sort=date. Use URL encoding for special characters in values.
There is no official limit in the HTTP spec, but practical limits exist. Most browsers support URLs up to 2,048 characters. Some servers limit URLs to 8,192 characters. For very long query strings, consider using a POST request with the data in the request body instead.
