Encode text to HTML entities or decode entities back to text. Convert special characters like <, >, &, and quotes to their corresponding HTML entities (e.g., <, >) to prevent them from being interpreted as HTML code. Crucial for web security and displaying code snippets.

?Frequently Asked Questions
Why do I need to encode HTML?
Browsers interpret characters like < and > as HTML tags. If you want to display these characters literally (e.g., showing a code snippet), you must encode them. Encoding also prevents malicious scripts from executing if user input is displayed on a page.
What is the difference between named and numeric entities?
Named entities (like ©) use a keyword. Numeric entities (like ©) use the character's ASCII/Unicode number. Numeric entities are more universally supported, but named entities are easier to remember.
