About URL encoder

URL encoding (also called percent encoding) converts characters that are not permitted in URLs — such as spaces, `&`, `=`, `#`, and non-ASCII characters — into a `%XX` hexadecimal format. For example, a space becomes `%20` and `&` becomes `%26`. The URL Encoder is useful when constructing query strings programmatically, passing special characters in URL parameters, building API request URLs that include user-generated text, and ensuring links remain valid when shared across different systems and platforms.
