HTML Entity Encoder / Decoder
HTML entities are special character sequences used to represent reserved and special characters in HTML documents. For example, "<" is written as <, and "&" as &. This tool encodes and decodes HTML entities.
Why HTML Entities Are Needed In HTML, some characters have special meaning: < and > denote tags, & starts an entity, " and ' are used in attributes. To display these characters as text, they must be replaced with HTML entities. This also prevents XSS attacks when outputting user data on a page.
Free online tool for encoding and decoding HTML entities. Convert special characters (<, >, &, ", ') to HTML entities (<, >, &, ", ') and back. Both named (&) and numeric (&, &) entities are supported.
HTML entities are necessary for correctly displaying reserved characters in HTML documents. The characters < and > are used for tags, & for starting entities, " and ' in attributes. Without escaping, these characters can break the HTML structure or create XSS vulnerabilities.
The tool is useful for web developers preparing content for HTML insertion, debugging code with HTML entities, and processing user input. All computations are performed locally in your browser — data is never transmitted anywhere.
