What are HTML entities?

HTML entities are special codes that represent reserved characters in HTML (like , &) or special symbols (like ©, €, →). Encoding them prevents rendering issues and XSS vulnerabilities.

Does it include a reference table?

Yes. The tool includes a comprehensive reference table of common HTML entities so you can quickly look up the code for any character you need.

Why should I encode HTML entities?

Encoding prevents browsers from interpreting special characters as HTML markup. This is essential for displaying code examples, preventing XSS attacks, and ensuring text renders correctly in all browsers.

What is the difference between named and numeric entities?

Named entities use readable names like & for &. Numeric entities use numbers like & for the same character. Both work identically in browsers, but named entities are more readable in source code.

Does it handle Unicode characters?

Yes. The encoder handles all Unicode characters, converting them to numeric HTML entities when they fall outside the standard ASCII range.

Can I use this to prevent XSS attacks?

Encoding HTML entities is one layer of XSS prevention. It converts characters like to < and > so they display as text rather than being interpreted as HTML tags. Always use server-side sanitization as well.
