# 🔐 URL Encoder/Decoder

Encode and decode URL strings with component-specific encoding, visual highlighting, and character reference tables

 

 

 #####  What is URL Encoding?

 **Percent-encoding**, also known as **URL encoding**, is a mechanism for encoding special characters in a Uniform Resource Identifier (URI). It's used to safely transmit data in URLs by replacing unsafe characters with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code.

 #####  Encoding Tips

- **RFC 3986 (Component):** Standard URL component encoding - encodes most special characters except: A-Z a-z 0-9 - \_ . ~
- **Query String:** Used in URL query parameters - spaces become '+' instead of '%20'
- **Form Data:** Used for application/x-www-form-urlencoded - similar to query string encoding
- **Reserved Characters:** : / ? # \[ \] @ ! $ & ' ( ) \* + , ; = should be encoded in most contexts
- **Unsafe Characters:** Space " < > # % { } | \\ ^ ~ \[ \] ` must always be encoded
