Security Tip

Always use HTML encoding when displaying user-generated content to prevent Cross-Site Scripting (XSS) attacks. Encoding converts dangerous characters like < into harmless entities like &lt;.

Quick Actions

What is the HTML Encoder/Decoder?

Think of the HTML Encoder/Decoder as a protective filter for your web content. In web development, certain characters like <, >, and & have special meanings in HTML. If you want to display these characters literally on a page without the browser interpreting them as code, they must be converted into "HTML Entities."

This tool serves a dual purpose: it ensures your code renders exactly as intended and provides a vital layer of security. By encoding user-generated content, you protect your application from Cross-Site Scripting (XSS) attacks, where malicious scripts are injected into web pages. It is a "Swiss Army knife" for developers, technical writers, and security professionals alike.

XSS Prevention

Always encode user-submitted text (like comments) before storing or displaying it to prevent malicious script injection.

SEO & Entities

Use entities for copyright symbols (&copy;) or trademarks to ensure they render correctly across all browsers and charsets.

Data Integrity

If your text contains intentional HTML tags that you don't want to encode, use the "Preserve" options carefully.
