What is URL encoding?

URL encoding (also called percent encoding) converts special characters like spaces, &, =, ? into %XX format so they can be safely transmitted in a URL. For example, a space becomes %20.

What is HTML entity encoding?

HTML encoding converts characters like , &, ", ' into HTML entities (<, >, &, ", ') to prevent them from being interpreted as HTML. This is critical for preventing XSS attacks.

What is Base64 used for?

Base64 encodes binary data as ASCII characters. It is used in data URLs, HTTP Basic authentication, email MIME attachments, and JSON Web Tokens (JWTs).
