- Paste your text. Enter the text to escape.
- Copy the result. Get the HTML-escaped version.

What Is HTML Encode?
Escaping HTML characters prevents them from being interpreted as markup, which is essential for safe rendering and preventing injection attacks.
What is HTML encoding?
Special characters are replaced with entities: < becomes <, > becomes >, & becomes &, and quotes become " or '. This makes the text display literally.
Why it matters for security
Unescaped user input can break layouts or enable XSS. Encoding input before rendering it as HTML prevents scripts from executing.
