What is URL Encoding?

URL encoding, also known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It is used to convert characters that are not allowed in a URL into a format that is acceptable for a URL.

When to Use URL Encoding

• When sending data in URL parameters
• When handling user input that will be part of a URL
• When working with APIs that require URL-safe parameters
• When creating links with special characters in them

URL Encoding vs. Component Encoding

There are two main types of URL encoding:

• Standard URL Encoding: Encodes spaces as '+' and preserves some characters like '/', '?', ':', '@', etc. that have special meaning in URLs. In JavaScript, this is similar to the encodeURI() function.
• Component Encoding: More aggressive encoding that converts all special characters to percent-encoded format, including '/', '?', etc. In JavaScript, this is similar to the encodeURIComponent() function. Use this when encoding individual components of a URL, such as query parameters.
