URL Encoder & Decoder

What Is URL Encoding?
URL encoding converts characters that may not be safe or valid inside a URL into a format that can be transmitted reliably over the internet.
For example, spaces and special characters can be represented using percent-encoded values. A space can become %20.
URL encoding is commonly used when working with query parameters, web forms, APIs and links containing special characters.
