HTML Encoder/Decoder
Encode and decode HTML entities
What is HTML Encoder & Decoder?
The HTML Encoder & Decoder is a free online tool that converts special characters to HTML entities and decodes HTML entities back to readable characters, all instantly in your browser. When displaying HTML code or user-submitted content on a web page, characters like <, >, &, and quotes must be encoded as HTML entities (<, >, &) to prevent browsers from interpreting them as actual HTML tags. Failing to encode these characters is one of the most common causes of Cross-Site Scripting (XSS) vulnerabilities in web applications. This tool is used by developers to safely display code snippets in documentation, encode user input before storing it in databases, and decode HTML entities received from APIs or legacy systems. It handles all standard HTML entities and Unicode numeric entities.
