HTML Encoder/Decoder

Security (XSS Prevention): Encoding user input prevents malicious scripts from being executed in the browser, protecting against cross-site scripting attacks
Display Code Examples: When showing HTML or XML code on a webpage, encoding ensures the code is displayed as text rather than rendered as HTML
Special Character Display: Show reserved HTML characters like &lt; , &gt; , and &amp; correctly in your content without breaking the HTML structure
Data Sanitization: Clean user-submitted data before storing it in databases or displaying it on web pages
Email Templates: Ensure email content displays correctly across different email clients by encoding special characters
XML/RSS Feeds: Properly encode content for XML-based formats where special characters have specific meanings

Encode HTML special characters to entities and decode HTML entities back to characters. Essential for web security and displaying code.

What is HTML Encoding?

HTML encoding (also known as HTML escaping) is the process of converting special characters into their HTML entity equivalents. For example, the less-than sign < becomes < and the ampersand & becomes &. This is essential for displaying these characters correctly in HTML and preventing security vulnerabilities like cross-site scripting (XSS) attacks.

When user input or code examples need to be displayed on a web page, encoding ensures that the browser interprets them as text rather than executable HTML or JavaScript. Our tool makes it easy to encode and decode HTML entities instantly and includes a reference of common HTML entities.
