What Is HTML Escaping?

HTML escaping is the process of converting special characters such as <, >, &, quotes and apostrophes into safe HTML entities so that browsers display them as plain text instead of executing them as markup.

Why HTML Escaping Is Important

• Prevents Cross-Site Scripting (XSS)
• Displays HTML code in tutorials
• Protects user-generated content
• Avoids script execution
• Improves web application security

Example of Escaped HTML

Original code: <script>alert("Hi")</script>

Escaped output: <script>alert("Hi")</script>

When You Should Escape HTML

• Displaying code blocks
• Saving comments in databases
• Accepting form inputs
• Rendering blog comments
• Building CMS systems

Difference Between Escape and Encode

HTML escaping and HTML encoding mean the same thing. Both convert special characters into entities so browsers treat them as readable text.

Common HTML Entities

• &lt; → <
• &gt; → >
• &amp; → &
• &quot; → "
• &#039; → '

Why Developers Use HTML Escape Tools

Manual escaping is error-prone. Automated tools ensure consistent encoding and reduce the risk of missing dangerous characters that may cause security issues.

Client-Side Privacy Protection

All HTML encoding occurs inside your browser. No content is uploaded, stored or transmitted to any server, ensuring full privacy and confidentiality.
