Free Online HTML Escape Tool

HTML escaping is a fundamental web security and development practice. When you need to display HTML code as text on a web page — rather than having the browser interpret it — special characters must be converted to their HTML entity equivalents. Our free online HTML escape tool does this instantly and correctly.

The five key characters that must be escaped are: < (becomes &lt;), > (becomes &gt;), & (becomes &amp;), double quotes (becomes &quot;), and single quotes (becomes &#039;). Without escaping, these characters would be interpreted as HTML tags, attributes, or entities rather than displayed as text.

This is critically important for security. Cross-Site Scripting (XSS) attacks exploit unescaped user input by injecting malicious HTML or JavaScript code. When user-supplied content is displayed without proper escaping, attackers can execute scripts in other users' browsers. HTML escaping neutralizes this threat by ensuring code is displayed as text, not executed.

Developers use HTML escaping when: displaying code snippets in tutorials or documentation, showing HTML source code on web pages, handling user-generated content in comments or forums, building dynamic content from user input, and creating HTML email content with special characters.

Bloggers and technical writers frequently need to escape code examples for their articles. Rather than manually replacing each special character, this tool handles the conversion instantly for any amount of HTML code.

The tool processes text entirely in your browser — no HTML is sent to any server. This makes it safe to escape code containing sensitive information like API keys or internal URLs.
