URL Encoder & Decoder

Percent-encode text for safe use in URLs, and decode encoded URLs back to readable text.

To URL-encode text, paste it above and unsafe characters are replaced with percent-escaped equivalents. Component mode also escapes reserved characters such as slashes and ampersands, which is what you need when placing a value inside a query string.
