What is URL Encoding?
URL encoding (also known as percent encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts special characters and spaces into a format that can be safely transmitted over the internet.
When you encode a URL, special characters like spaces, ampersands, and question marks are replaced with percent-encoded sequences. For example, a space becomes %20, and an ampersand becomes %26.
URL encoding is essential for web development, API testing, and data transmission. It ensures that URLs are properly formatted and can be safely used in web applications without causing errors or security issues.
