Free HTML Entity Converter — Encode & Decode HTML Entities Online

What Is an HTML Entity Converter?

An HTML entity converter is a tool that encodes special characters into their HTML entity equivalents — and decodes them back. HTML entities are special codes that represent characters which have reserved meanings in HTML (like <, >, &) or characters not available on a standard keyboard (like ©, €, —). Our free tool handles both encoding and decoding instantly.

Why HTML Entities Matter

Using HTML entities correctly is critical for web security, proper rendering, and code validity. If you include raw < or & characters in HTML, browsers may misinterpret them as tags or entity references — breaking your layout or creating security vulnerabilities (XSS attacks). HTML entities ensure your content displays exactly as intended across all browsers and devices.

Common HTML Entities

Reserved Characters

• < → < (less than)
• > → > (greater than)
• & → & (ampersand)
• " → " (double quote)
• ' → ' (apostrophe)

Typography & Symbols

• © → © (copyright)
• ® → ® (registered)
• ™ → ™ (trademark)
• — → — (em dash)
• € → € (euro sign)

Numeric Entities

Every Unicode character can be represented as a numeric entity: © (decimal) or © (hexadecimal) both produce ©. Numeric entities work when named entities are not available for a character.

How to Use the HTML Entity Converter

1. Open the HTML Entity Converter tool above
2. Paste your text or HTML code into the input field
3. Select Encode to convert special characters to HTML entities, or Decode to convert entities back to readable characters
4. Click the convert button to process your text
5. Copy the result and use it in your HTML code, CMS, or email templates

Common Use Cases

• Web development — Safely embed special characters in HTML without breaking markup
• CMS content editing — Fix display issues with special characters in WordPress, Joomla, or Drupal
• Email templates — Encode characters that email clients may misrender
• Security — Prevent XSS (Cross-Site Scripting) attacks by encoding user input
• Data migration — Decode HTML entities when moving content between systems

Best Practices

• Always encode user input — Never render raw user input in HTML without encoding
• Use named entities for readability — & is clearer than & in source code
• Use numeric entities for rare characters — Named entities aren't available for every Unicode character
• Set UTF-8 encoding — Use to minimize the need for entities
• Test across browsers — Verify entity rendering in Chrome, Firefox, Safari, and Edge

Frequently Asked Questions

What's the difference between HTML encoding and URL encoding?

HTML encoding converts characters to HTML entities (e.g., &) for safe display in web pages. URL encoding converts characters to percent-encoded format (e.g., %26) for safe use in URLs. They serve different purposes — use HTML entities in page content and URL encoding in links and query strings.

Do I need HTML entities if my page uses UTF-8?

With UTF-8 encoding, most characters display correctly without entities. However, you must still encode the five reserved HTML characters (<, >, &, ", ') to avoid breaking your HTML structure. Entities are also useful for invisible or hard-to-type characters.

Can this tool handle bulk text conversion?

Yes. Paste any amount of text into the converter and it will process all characters at once. There's no practical size limit for typical use cases.

What is XSS and how do HTML entities prevent it?

XSS (Cross-Site Scripting) is an attack where malicious scripts are injected into web pages. By encoding characters like < and > as HTML entities, you prevent browsers from interpreting injected code as executable HTML or JavaScript — neutralizing the attack.
