URL Component Encoder and Decoder

How to use this tool

Use the controls to percent-encode or decode a component such as a query parameter value. For example, a space is represented as %20 by encodeURIComponent.

Limits and safe use

This page handles URL components, not complete URLs with structural separators. For a whole URL, use the browser URL API and encode individual parameter values so delimiters remain meaningful.
