Free Online HTML Entity Encoder & Decoder
Safeguard your website's integrity and sanitize your code snippets with our Simple HTML Entity Tool. Many special characters such as <, >, and & have specific functional meanings in HTML and can cause rendering issues or security vulnerabilities if not properly escaped. Our utility allows you to instantly encode these characters into their decimal entity equivalents, ensuring they are displayed as plain text without being interpreted as active code by the browser. You can also decode existing entity strings back into readable HTML for documentation and auditing purposes.
Secure Sanitization
Prevent malicious code execution and rendering broken layouts by properly escaping special characters for web display.
Unicode Precision
Our engine handles a wide range of symbols and international characters, mapping them to standard Unicode-safe HTML entities.
Private Operations
Your source code remains confidential. All encoding and decoding cycles occur locally on your machine within the browser sandbox.
