HTML Encoder

About this tool

What is an HTML Encoder? HTML Encoder An encoding tool that converts special characters in HTML into their equivalent HTML entities. It is used to ensure that text entered by users is displayed as plain text rather than executable HTML code, thereby preventing XSS (Cross-Site Scripting) attacks. Key Features Encodes all special HTML characters (& " ') into entities Encoding options ranging from minimal to full Encoding mode for URLs within HTML attributes Display input and output side by side Copy the result with a single click How does it work? Paste text containing special HTML characters, and the tool will convert each character to the equivalent HTML entity. For example, <script> becomes <script>. Practical example: You are developing a comment system for a website and need to display user comments securely. A user writes <script>alert('XSS')</script> in a comment. Before saving it to the database, you pass the text through an HTML encoder, which converts the malicious code into safe text entities that appear as plain text on the page instead of being executed. Common Use Cases Validating User Input: Encoding user comments and messages before displaying them on the page Protection against XSS: Prevent malicious JavaScript code from being executed via input fields Rendering programmatic content: Display HTML or JavaScript code as plain text on
