Question 1

What is a URL query string?

Accepted Answer

A query string is the part of a URL that comes after the question mark (?). It contains key-value pairs separated by ampersands (&) that pass data to the web server or client-side script. Example: ?name=John&age=30.

Question 2

What does URL decoding mean?

Accepted Answer

URL encoding replaces special characters with percent-encoded sequences (e.g., space becomes %20). URL decoding reverses this, converting encoded sequences back to their readable characters. Our tool shows both the raw encoded value and the decoded version.

Question 3

Can I paste a full URL or just the query string?

Accepted Answer

You can paste either a complete URL (https://example.com?key=value) or just the query string portion (?key=value or key=value). The parser handles both formats automatically.

Question 4

Can I export the parsed parameters?

Accepted Answer

Yes. Use the 'Copy as JSON' button to copy all parsed parameters as a JSON object to your clipboard, which you can then paste into your code or any other tool.

Question 5

Are duplicate parameter names supported?

Accepted Answer

Yes. Some URLs use the same parameter name multiple times (e.g., ?tag=a&tag=b). The parser displays each occurrence as a separate row in the results table.
