Complete Guide to HTML Encoding and Decoding
HTML encoding is a critical web development practice that converts special characters into HTML entities to ensure safe display and prevent security vulnerabilities. Whether you're protecting against XSS attacks, displaying user-generated content, or preparing data for web storage, proper HTML encoding is essential for maintaining both security and proper text rendering in web browsers.
How to Use the HTML Encode/Decode Tool

HTML Encode/Decode Tool - Frequently Asked Questions
What is the difference between HTML encoding and decoding?
HTML encoding converts special characters (like <, >, &, ") into HTML entities (<, >, &, ") for safe display. Decoding reverses this process, converting entities back to readable characters.
Why is HTML encoding important for web security?
HTML encoding prevents XSS (Cross-Site Scripting) attacks by ensuring that user input containing HTML or JavaScript code is displayed as text rather than executed as code. This is crucial for any website that displays user-generated content.
Which characters are commonly HTML encoded?
The most common characters that need encoding are: < (<), > (>), & (&), " ("), and ' ('). Additionally, non-ASCII characters like accented letters may be encoded for compatibility.
Can this tool handle non-English characters?
Yes, the tool properly handles international characters, accented letters, and Unicode characters, converting them to their appropriate HTML entity equivalents when encoding.
