What input formats are accepted?

You can paste a complete URL such as https://site.com/x?a=1, a string that starts with ?, or just the raw query string a=1&b=2. Any #fragment is ignored.

Are values URL-decoded?

Yes. Percent-encoded sequences like %20 and plus signs used for spaces are decoded so you see the real value, such as "hello world".

Is anything uploaded?

No. Parsing happens entirely in your browser and your URLs are never sent to a server.

Query String Parser

Split a URL query string into decoded key/value pairs.

Parse any query string into key/value pairs

Paste a URL or query string and instantly see every parameter broken out into a clean key and decoded value table. Percent-encoding and + spaces are decoded for you, and repeated keys (like tags=a&tags=b) each get their own row.

Useful for debugging links, inspecting tracking parameters, or checking what an API call actually sends. Everything runs in your browser — nothing is uploaded.
