HTML Escape
Escape HTML special characters to prevent XSS attacks.
🌐 Escapes & < > " and '. Use before inserting user input into HTML to prevent XSS.
What Is This Tool?
HTML escaping converts special characters (& < > ") into their entity equivalents (& < >), so they display correctly in a browser and prevent XSS attacks.
Why Escaping Matters
If user input contains <script> and you insert it into a page without escaping, the browser runs the script — a classic XSS (cross-site scripting) attack. Escaping turns it into harmless text that displays as <script>instead of executing.
What Gets Escaped
&→&(must be escaped first)<→<>→>"→"'→'
Escaping for Different Contexts
Escaping rules differ by where text will appear. HTML body escaping (this tool) is different from attribute escaping, URL escaping, or JavaScript string escaping. Always escape for the specific context — using the wrong one can leave vulnerabilities.
Frequently Asked Questions
Is this enough to prevent all XSS?
HTML body escaping covers the most common case, but XSS has many variants (attribute-based, script-based, URL-based). Use a reputable library like DOMPurify for untrusted HTML.
