About This Calculator
When you write HTML, characters like <, >, and & are interpreted as markup. This encoder converts them into their entity form (<, >, &) so they display as literal text.
Choose the encode set to match the context: plain text (< > &), attribute values (also "), or all common characters. Encoding runs locally in your browser.

Frequently Asked Questions
Why should I escape HTML?
Escaping prevents special characters from being interpreted as tags, which is essential for properly displaying user-generated content and avoids broken layouts.
What is the difference between modes?
In regular HTML text only <, >, and & need escaping. Inside a double-quoted attribute, you must also escape ". The "all" mode also escapes single quotes for safety.
