A URL (Uniform Resource Locator) is the address of a resource on the internet. A complete URL consists of a protocol (e.g. https://), hostname (domain), port number, path, query parameters, and fragment identifier (hash). For example, https://example.com:443/path?key=value#section is a complete URL containing all components.

What is URL encoding and why is it needed?

URL encoding (percent-encoding) converts special characters to %XX format, ensuring that URLs do not contain illegal characters. For example, spaces are encoded as %20, and Chinese characters are encoded as multiple %XX sequences. Browsers and servers handle encoding/decoding automatically, but special care is needed when manually building URLs or API requests.

How are multiple same-name keys handled in query parameters?

The URL standard allows multiple query parameters with the same name, e.g. ?arr=1&arr=2. This tool fully parses all parameters, including each value of duplicate keys. You can also add parameters with the same name during editing, which is useful for API scenarios that need to pass array values.

Why can't some URLs be parsed?

This tool uses the browser's native URL API for parsing, which requires the input to include a protocol (e.g. http:// or https://). Relative paths (e.g. /path/to/page) and incomplete URLs (e.g. example.com) cannot be parsed. Please ensure you input a complete URL with a protocol.
