What are the parts of a URL?+
A URL has: protocol (https), hostname (example.com), port (443), path (/page), query string (?key=value), and fragment (#section). Not all parts are required.
What is the difference between a URL and a URI?+
A URI (Uniform Resource Identifier) is the general concept. A URL (Uniform Resource Locator) is a URI that also specifies how to retrieve the resource (via a protocol like http or ftp). In practice, 'URL' and 'URI' are used interchangeably for web addresses.
How do I decode a URL-encoded query parameter?+
Paste the full URL into this tool and each query parameter is decoded and shown as a human-readable key-value pair. Or use the URL Encoder/Decoder tool for individual strings.
What is a URL fragment (#)?+
The fragment (hash) identifies a section within the page, like #section-2. Fragments are never sent to the server - they're processed by the browser only.
