## What does this tool do?

URLs can only contain a limited set of ASCII characters. Percent-encoding (also called URL
encoding) replaces reserved or non-ASCII characters with a `%` followed by two hex digits — for
example a space becomes `%20`. This tool encodes text into percent-encoded form and decodes it
back, entirely in your browser.

## When you need it

You use URL encoding when building query strings, form data or links with special characters.
Encoding is **not** encryption: it only makes text safe to put in a URL.
