URL parser
Breaks a URL down into its scheme, host, port, path and query parameters.
Parse a URL into its separate constituent parts (protocol, origin, params, port, username-password, ...)
Steps and notes
What is URL parser?
This tool applies the browser's native URL parser to whatever you paste and lays out every component the spec recognizes: protocol, username, password, hostname, port, pathname, query parameters (each key and value on its own row) and fragment. Using the same parser as the browser matters because URL edge cases are genuinely subtle — default ports are hidden, percent-encoding is normalized, and internationalized domain names are converted to punycode. When a redirect, an allowlist check or a routing rule is not behaving as expected, parse the exact string here first; the discrepancy between what you think the URL is and what the parser sees is usually the bug.
- Paste the full URL
- Read the parsed fields
- Query parameters are listed as a table for easy copying
Frequently asked questions
- Why is the port missing from my parsed URL?
- Default ports are not written in URLs: https implies 443 and http implies 80, and the browser's parser reports an empty port for them. The URL is not "missing" anything — the scheme determines the port automatically.
- Can a URL with a username and password be safe?
- Basic-auth credentials in a URL (https://user:pass@host) are visible in logs, browser history and Referer headers, and several browsers now strip or block them. The parser shows them so you can audit links — production systems should send credentials via headers instead.
- What does the #fragment part mean for the server?
- Nothing: the fragment is never sent to the server, it stays in the browser (for anchor jumps or, in SPA frameworks, as client-side routing). Two URLs differing only in fragment are the same request to a server.
