Frequently Asked Questions
What is an HTML Entity?
An HTML entity is a piece of text (starting with an ampersand & and ending with a semicolon ;) used to display reserved or invisible characters in HTML. For example, < displays the less-than sign <.
Why do I need to encode HTML?
If you want to display HTML code visually on a webpage (like a code snippet), you must encode it. Otherwise, the browser will interpret the code and render it, breaking your page layout or potentially running malicious scripts.
Is the decoding process secure?
Yes. The decoding function utilizes the browser's native DOM parsing in a secure, non-executable environment (via a disconnected textarea element), which prevents scripts from running while extracting the text.
