About the URL Parser

The URL Parser breaks any web address into its individual components - protocol, username, password, hostname, port, pathname, query string, and fragment - all displayed in a clean, readable layout. Query parameters are automatically extracted into their own table with individual copy buttons. All parsing happens entirely in your browser using the native URL API.

Common use cases

Frequently Asked Questions

How does the URL Parser work technically?

The URL Parser uses the browser's built-in URL Web API - specifically new URL(input) - which is the same standards-compliant parser that browsers use internally when fetching resources. This means the tool handles edge cases like percent-encoding, international domain names (IDN/Punycode), default port omission, and relative path resolution exactly as a real browser would. Query parameters are then enumerated via URLSearchParams, which correctly handles repeated keys and encoded values.

Is my URL data private and secure?

Yes - the URL Parser runs entirely in your browser using client-side JavaScript; no URL or query parameter data is transmitted to any server. This makes it safe to paste internal API endpoints, authentication callback URLs containing tokens, or staging environment addresses without risk of exposure. The tool does not log, store, or cache any input between sessions.

What types of URLs does the parser support, and are there any limitations?

The parser supports any URL conforming to the WHATWG URL standard, including http://, https://, ftp://, ws://, and wss:// schemes. It does not parse relative URLs (e.g. /path/to/page) without a base, and some non-standard schemes like mailto: or data: may not expose all components. Very long URLs - such as those with large base64-encoded payloads in query strings - are handled fine since the parsing is memory-local in your browser tab.

Which browsers are compatible with this URL Parser?

The tool relies on the WHATWG URL API and URLSearchParams, which are supported in all modern browsers including Chrome 32+, Firefox 36+, Safari 10+, and Edge 17+. Internet Explorer does not support this API natively, so IE users would see an error; however, IE represents a negligible fraction of traffic in 2024. For the best experience, use an up-to-date Chromium-based browser or Firefox.

How does this compare to parsing URLs with code or using curl?

Tools like curl -v, Python's urllib.parse, or Node's url.parse can all decompose a URL, but they require switching to a terminal or writing code snippets. This visual parser gives you an instant, labeled breakdown without opening a terminal - ideal when you need to quickly verify a redirect chain, check OAuth scopes in a callback URL, or confirm that UTM parameters are correctly formatted. It also provides one-click copy buttons for each component, saving time when you need to paste individual parts into other tools.
