What is HTML encoding
Converts characters with special meaning in HTML — like <, >, & and quotes — into entities (<, >, &) so they display as literal text instead of being interpreted as code.
When to use it
Essential for displaying source code inside a web page, or to prevent user-typed text from being interpreted as HTML/script (basic XSS prevention).
Frequently asked questions
Why do I need to encode HTML?
To display characters like < and > as literal text instead of having the browser interpret them as part of the page's code.
Does this protect against XSS attacks?
It helps as a basic layer, but doesn't replace proper validation and sanitization on the backend.
