URL Encoder / Decoder

About URL Encoder / Decoder

Encode or decode full URLs, individual URL components, and form query strings. Inspect percent-encoding and reserved characters directly in your browser.

How to use this tool

Choose encode or decode and the URL, component, or form-query mode. Paste the value and inspect how reserved characters are handled.

What to know

A full URL and a query parameter need different escaping. In form encoding, a plus sign can represent a space; Base64 is a different encoding.
