URL Query String Parser – Parse and edit URL parameters
The URL Query String parser breaks down URL parameters (query string) into a clear format and allows for their modification. Paste a URL into the field and see all parameters as key-value pairs.
The tool automatically URL-encodes and decodes parameters and displays the structure clearly. You can add, edit, and remove parameters and copy the modified URL. Perfect for developers debugging API calls.
How does URL query string work?
URL query string starts with a question mark (?), parameters are separated by &, and key-value pairs are joined with =. For example, `https://example.com/search?q=test&lang=en&page=2` contains three parameters: q=test, lang=en, page=2. Special characters are encoded (%20 = space, %2F = forward slash). The parser automatically decodes the encoding.

Enter a URL, and the tool parses query string parameters into a readable list.
- Parse URL parameters into key-value pairs in readable format.
- Decode URL-encoded characters (%20, %3D, etc.) to plain text.
- Copy individual parameters or entire parsed structure.
Parameters are key=value pairs after the URL's ? that transfer data between pages.
- Parameters are separated by &: ?key1=value1&key2=value2.
- URL encoding converts special characters to safe format – parser decodes them.
- Duplicate parameters or empty values may indicate faulty URL structure.
URL parameters may contain sensitive information – handle them carefully.
- Don't share URLs containing tokens, passwords, or personal data.
- Tool processes URLs entirely in browser – no data sent externally.
- Many analytics tools (UTM parameters, etc.) have their own standard parameters.
