Why Use HTML Entities?
Reserved Characters: Characters like <, >, and & have special meaning in HTML and must be encoded to display correctly.
Special Symbols: Display symbols like copyright (©), trademark (™), and currency symbols that may not be on your keyboard.
Unicode Support: Represent any Unicode character using numeric entities.
XSS Prevention: Encoding user input helps prevent cross-site scripting attacks.
Frequently Asked Questions
Is my data sent to a server?
No. All encoding and decoding happens entirely within your browser. Your text is never transmitted to our servers or stored anywhere.
What's the difference between named and numeric entities?
Named entities use descriptive names like & while numeric entities use Unicode code points like & or &. Both represent the same character.
Do I always need to encode special characters?
Only when displaying HTML code within HTML, or when characters might be interpreted as markup. In normal text content, most characters display fine.
Can I encode all Unicode characters?
Yes! Any Unicode character can be represented as a numeric entity. Characters without named entities will be converted to decimal (&) or hexadecimal (&) format.
What about non-breaking spaces?
The non-breaking space ( or  ) is a special entity that prevents line breaks at that position, commonly used for formatting.
