What This Tool Does
The HTML Escape/Unescape tool converts special HTML characters to their entity equivalents and reverses the process. Escaping transforms characters like less-than, greater-than, ampersands, and quotes into HTML entities (<, >, &, ") so they display as text rather than being interpreted as HTML markup. Unescaping converts entities back to original characters. The tool ensures text containing HTML-like characters displays safely in web pages, prevents XSS vulnerabilities, and makes encoded HTML readable again for editing or analysis.
Why This Tool Is Useful
Displaying user-generated content containing HTML characters requires escaping to prevent browser interpretation as markup. Without escaping, angle brackets create unintended tags, potentially breaking layouts or enabling XSS attacks. Code examples in documentation need escaping to display HTML tags as text. API responses often contain escaped HTML that needs unescaping for readability. Developers debugging HTML output need to see actual characters instead of entities. Manual escaping is tedious and error-prone. The tool automates bidirectional conversion, ensuring safe HTML display and making escaped content readable.
How To Use This Tool
- Choose whether to escape text to HTML entities or unescape entities to characters
- For escaping: paste text containing HTML special characters
- For unescaping: paste HTML with entity codes like < or &
- Click escape or unescape button to transform input
- Copy result for safe HTML display or readable text
Common Use Cases
- User Content Display: Escape user-generated content before displaying in HTML
- Code Examples: Escape HTML code samples for display in documentation
- XSS Prevention: Escape untrusted input to prevent cross-site scripting
- API Debugging: Unescape HTML entities in API responses for readability
- Data Migration: Process escaped HTML during content migration
Tips For Best Results
Always escape user-generated content before displaying in HTML. Remember escaping is not complete XSS protection—use Content Security Policy and input validation too. When unescaping, verify the source is trusted. Double-escaping can occur if content is escaped multiple times. Test escaped content displays correctly in your target environment.
Benefits of Using This Tool
HTML escaping tools prevent security vulnerabilities and display issues. Developers ensure user content displays safely without breaking layouts. The tool automates tedious character conversion. Quick escaping access during development prevents XSS bugs. Unescaping makes debugging API responses faster. Browser-based operation requires no library installation or code.
Example
Escaping
Input: <div>Hello & Welcome</div>
Output: <div>Hello & Welcome</div>
Unescaping
Input: <p>Text</p>
Output: <p>Text</p>
