URL Encode/Decode

URL Encode/Decode

URL encoding (also known as percent-encoding) is a way of encoding special characters in a URL so that it can be transmitted over the Internet.

When a URL is transmitted over the Internet, certain characters in the URL are interpreted as special characters that have a specific meaning. For example, the character "#" is used to indicate the start of a fragment identifier, and the character "&" is used to separate query parameters.

To encode these special characters, they are replaced with a percent symbol ("%") followed by the two-digit hexadecimal representation of the ASCII character. For example, the space character is encoded as "%20", the "#" character is encoded as "%23", and the "&" character is encoded as "%26".

URL encoding is used to ensure that URLs are properly formatted and can be transmitted over the Internet without any issues. It is particularly important when transmitting URLs in HTTP headers or in HTML forms, as these URLs may contain special characters that could cause problems if they are not properly encoded.
