URL parser

Break a URL into its components, inspect repeated query parameters, and resolve relative paths.

Inside the address

protocol: https:
username: —
password: —
hostname: example.com
port: —
origin: https://example.com

How it works & useful details

How this tool works

WHATWG URL parsing accepts absolute schemes and resolves relative paths only with an explicit base. Host casing, default ports and path segments may normalize. Parsing does not verify a destination. Query values use forgiving URLSearchParams decoding; decoded components keep malformed percent escapes unchanged. Limit: 8,192 characters per URL.
