URL Encoder/Decoder

Percent-encode text for safe use in URLs or decode an encoded URL component.

Percent-encode text for safe use in URLs or decode an encoded URL component.

How to use

Encoding applies percent-encoding to every character that is not safe inside a URL component, and decoding reverses it. Malformed percent sequences are reported as errors.

Example

Encoding "a b&c=d" produces "a%20b%26c%3Dd", safe to place in a query string.
