About the HTML Entity Encoder & Decoder
HTML entities let you show characters that would otherwise be read as markup, such as < and &, or that are hard to type, such as © and €. Encoding text before inserting it into a page prevents broken layouts and is an important part of preventing cross-site scripting (XSS).
This tool encodes the essential characters (&, <, >, ", ') and can optionally convert every non-ASCII character to a numeric entity. Decoding understands all named entities supported by browsers as well as decimal (©) and hexadecimal (©) forms.

Frequently asked questions
Which characters must be escaped in HTML?
In text content, & and < must be escaped. Inside attribute values, the quote character used to wrap the attribute must also be escaped. Escaping >, " and ' as well is a safe default.
Does encoding protect against XSS?
Escaping user input before inserting it into HTML text is a key defence, but context matters: URLs, JavaScript and CSS need their own escaping rules.
What is the difference between &copy; and &#169;?
They produce the same © symbol. The first is a named entity, the second a numeric (decimal) entity. Numeric entities work for every Unicode character.
