URL TOOLS

Query String Parser

Parses a URL query string into individual key/value pairs. Paste the full URL or just the query portion.

Runs entirely in your browser

How it works

URL encoding uses the browser's built-in encodeURIComponent and decodeURIComponent functions. Query string parsing uses the native URLSearchParams API. Everything runs locally using browser-native APIs.

Your data stays local

All encoding, decoding, and parsing happens inside your browser tab. The URLs and query strings you enter are never sent to a server.

Frequently asked questions

What can I paste in?

A full URL (https://...) or just the query string portion (?key=value&...).

Are encoded values decoded?

Yes — all percent-encoded values and + signs are decoded automatically.

Is there a limit to the number of parameters?

No practical limit — the tool handles URLs with hundreds of parameters.
