What is HTML Encoding and Decoding?

HTML encoding turns special characters into safe entities so browsers don’t confuse them with code. Example: < becomes <.

This prevents errors and protects websites from XSS attacks.

HTML decoding is the reverse, it changes encoded entities like < back into < so text displays correctly.
