Quick URL Encode / Decode
Quickly test individual strings against standard RFC 3986 percent-encoding.

Processed entirely in your browser using the native URL API. No URLs are sent to our server.
Complex URLs often carry dozens of tracking tags (UTM parameters), authentication tokens, deep-link paths, and hash fragments that are difficult to read in a single address bar.
The ToolDuck URL Parser breaks any URL down into its constituent RFC 3986 components, renders query parameters in an interactive table with individual copy buttons, and includes an instant URL encoder/decoder.
How to use this tool
- Paste any URL into the input field.
- Click Parse URL to decompose the link.
- Review the Protocol, Hostname, Path, and individual Query Parameters in the generated table.
- Use the Quick URL Encode / Decode tool below to test percent-encoding.
Anatomy of a Uniform Resource Locator (URL)
A standard URL consists of several distinct sections: Scheme (protocol like https), Authority (hostname and optional port), Path (the resource location on the server), Query String (key-value pairs starting with ?), and Fragment (client-side anchor starting with #).
Parsing these components accurately is critical when configuring API webhooks, redirect routers, and marketing campaigns.
Percent-encoding and reserved characters
Characters that have special meaning in URLs (such as ?, &, =, /, and spaces) must be percent-encoded when used as parameter values (for example, a space becomes %20, and & becomes %26).
Our interactive encoder/decoder handles standard UTF-8 percent-encoding cleanly in your browser.
Frequently asked questions
Does this tool transmit my URL over the internet?
No. All parsing, parameter extraction, and encoding operations execute inside your browser using the native JavaScript URL API.
Can it parse URLs with authentication credentials?
Yes. URLs with embedded usernames and passwords (e.g., https://user:pass@example.com) are parsed and separated into distinct fields.
