Free HTML Entity Encoder & Decoder - Convert Special Characters
Encode and decode HTML entities instantly. Convert special characters for safe HTML display and prevent XSS attacks.
What is HTML Entity Encoder?
Our HTML Entity Encoder & Decoder helps you convert special characters to HTML entities and vice versa. Essential for displaying special characters safely in HTML, preventing XSS attacks, and ensuring text renders correctly across all browsers and platforms.
HTML entities are special codes that represent characters which have special meaning in HTML (like <, >, &, ") or characters that aren't on standard keyboards (like €, ©, ñ). Encoding converts these to safe representations like <, >, & that browsers display correctly without interpreting as HTML code.
The tool handles both named entities ( , ©) and numeric entities (©, ©) bidirectionally. Choose full encoding (all special chars), selective encoding (only HTML-reserved chars), or decode entities back to readable characters. Perfect for developers, content creators, and SEO professionals.
All encoding happens locally in your browser. Your HTML content never leaves your device, making it safe for processing production code, customer data, or sensitive content that needs proper HTML escaping.

Frequently Asked Questions
Everything you need to know about HTML Entity Encoder
HTML entities are codes that represent special characters. Use them for: 1) Characters with special meaning in HTML (<, >, &, ") to display them literally without being interpreted as code; 2) Characters not on standard keyboards (©, €, ñ); and 3) Preventing XSS attacks by encoding user input. For example, < displays as < without creating an HTML tag.
Named entities use descriptive names ( for non-breaking space, © for ©), making code more readable. Numeric entities use character codes (© or © for ©) and can represent any Unicode character. Named entities are easier to remember for common symbols, but only a limited set exists. Numeric entities can represent any character but are less readable.
Not always! Only encode characters that could cause issues: HTML reserved characters (<, >, &, ", ') must be encoded when displaying as text. For other special characters (©, €, ñ), you can use entities or Unicode directly if your HTML has proper charset (UTF-8). Encoding everything makes HTML harder to read in source but is safer for untrusted user input.
XSS (Cross-Site Scripting) works by injecting malicious HTML/JavaScript into pages. If you display user input like "<script>alert('hacked')</script>" directly, it executes! But encoding it to "<script>..." makes it display as text instead of executing. Always encode user-generated content before displaying in HTML to prevent attackers from injecting scripts.
Yes! Paste entire HTML documents and the tool decodes all entities at once. This is useful when you receive HTML with entities and want to read the actual characters, or when working with legacy code that over-uses entities. The tool handles mixed content with both named and numeric entities simultaneously.
Never! All encoding and decoding happens entirely in your browser using JavaScript. Your HTML content, user data, or text is processed locally and never uploaded to any server. This makes it completely safe for processing production HTML, customer content, or sensitive data that cannot leave your organization.
