Why Use HTML Entity Encoder?

XSS Prevention

Encoding HTML entities prevents cross-site scripting attacks by escaping dangerous characters.

Encode & Decode

Switch between encoding and decoding modes to convert in either direction instantly.

3 Entity Formats

Choose named entities (&amp;), numeric (&#38;), or hexadecimal (&#x26;) encoding formats.

100% Private

All processing happens in your browser. Your text is never sent to any server.

Non-ASCII Support

Optionally encode all non-ASCII characters for maximum compatibility across systems.

Entity Reference

Built-in reference table showing common HTML entities for quick lookup.

Common Uses for HTML Entity Encoder

Web Security

Encode user input before displaying in HTML to prevent XSS attacks.

HTML Development

Safely display code snippets and special characters in web pages.

Email Templates

Encode special characters in HTML emails for consistent rendering across clients.

Data Processing

Encode/decode text when working with HTML content in databases or APIs.

How It Works

1

Choose Direction

Select Encode to convert text to HTML entities, or Decode to convert entities back to text.

2

Enter Your Text

Paste or type your text in the input area. For encoding, choose your preferred entity format (named, numeric, or hex).

3

Copy the Result

The converted text appears instantly. Copy to clipboard with one click and use in your HTML code.

Tips & Best Practices

Always Encode User Input

When displaying user-submitted content in HTML, always encode it first to prevent XSS attacks.

Named Entities for Readability

Use named entities when possible (&amp;copy; instead of &#169;) - they make your HTML more readable.

Double Encoding

Be careful not to double-encode text. If text is already encoded, decoding then re-encoding may produce unexpected results.

Frequently Asked Questions

HTML entities are special codes used to represent characters that have special meaning in HTML (like < and >) or characters not available on a keyboard. For example, &lt; represents '<' and &amp; represents '&'.
Encoding prevents XSS (Cross-Site Scripting) attacks and ensures special characters display correctly in HTML. Without encoding, a '<' character might be interpreted as the start of an HTML tag instead of displaying as text.
Named entities use descriptive names (like &amp; for &), while numeric entities use character codes (like &#38;). Both work the same, but named entities are more readable. Hex uses hexadecimal codes (like &#x26;).
Yes! Use the 'Decode' mode to convert HTML entities back to their original characters. This is useful when working with escaped HTML content.
The five characters that must always be encoded in HTML are: & (ampersand), < (less than), > (greater than), " (double quote), and ' (single quote/apostrophe).
Yes, all encoding and decoding happens entirely in your browser using client-side JavaScript. Your data is never uploaded to any server.
