HTML entities are special codes used to represent characters that have special meaning in HTML, like < (less than), > (greater than), & (ampersand), and " (quotation mark). They start with & and end with ;.
Encoding HTML entities prevents browsers from interpreting special characters as HTML markup. This is essential for security (preventing XSS attacks) and for displaying code snippets on web pages.
The most important characters to encode are & (&), < (<), > (>), " ("), and ' ('). This tool also encodes other special characters into their numeric HTML entity equivalents.
