URL Encoder / Decoder

What is URL Encoding?

URL Encoding (Percent-encoding) is a mechanism for converting characters that have special meaning in URLs (like spaces, ?, &, =) into a safe, valid format. For instance, a space becomes %20.

How to use

1. To Encode: Select "Encode" mode. Paste your raw URL parameter or text. It will be converted into a safe string that you can use in a web address.
2. To Decode: Select "Decode" mode. Paste a percent-encoded string (e.g., Hello%20World) to see the original text.
