HTML Entity Encoder/Decoder
Convert special characters to HTML entities and vice versa.
📖 How It Works
What are HTML Entities?
HTML entities are special codes used to display reserved characters in HTML. For example,
the less-than sign (<) must be written as < to prevent browsers from
interpreting it as an HTML tag.
Common HTML Entities
<→ < (less than)>→ > (greater than)&→ & (ampersand)"→ " (double quote)'→ ' (single quote/apostrophe) → non-breaking space©→ © (copyright)®→ ® (registered trademark)
🔐 Security Tip: Always encode user input before displaying it in HTML to prevent XSS (Cross-Site Scripting) attacks. This tool helps you do exactly that!

❓ Frequently Asked Questions
Encode when displaying user-generated content, showing code examples, or inserting dynamic text into HTML attributes. This prevents browsers from misinterpreting special characters as HTML markup.
Named entities use descriptive names (like &) while numeric entities use character codes (like &). Both represent the same character. Named entities are more readable but not all characters have named versions.
