Encode and decode HTML entities
HTML entities are special codes used to represent characters that have special meaning in HTML, such as angle brackets, ampersands, and quotation marks. If these characters appear in web page content without being properly encoded, they can break the HTML structure or create security vulnerabilities. Our HTML Entity Encoder converts special characters into their safe HTML entity equivalents, while the Decoder converts entities back to readable characters.
This tool is essential for web developers who need to display code snippets in web pages, sanitize user input, or debug HTML rendering issues. The encoder handles the five most critical HTML entities: ampersand, less-than, greater-than, double quote, and single quote. All processing is done entirely in your browser.
