🛡️ HTML Entities
Safely encode special characters into HTML entities or decode them back to plain text.
How to Encode/Decode HTML Entities Online
This premium utility allows you to instantly escape HTML characters to prevent them from rendering or being executed by browsers, and reverse the process by unescaping them.
- Encode HTML: Converts reserved characters like
<,>,&,", and'into their safe entity forms (e.g.,<). - Decode HTML: Reverts entity codes back to their original readable characters.
Why HTML Encoding is Critical
HTML has special reserved characters that define its structure. If you want to write a tutorial displaying a `
` tag, writing it directly will cause the browser to create an invisible divider rather than display the text. By encoding it as `<div>`, the browser knows to render the literal text.
Furthermore, encoding user input before displaying it is the primary defense against Cross-Site Scripting (XSS) attacks, where malicious scripts are injected into trusted websites.
Frequently Asked Questions
What is an HTML Entity?
An HTML entity is a piece of text that begins with an ampersand (&) and ends with a semicolon (;). Entities are frequently used to display reserved characters (which would otherwise be interpreted as HTML code).
Why do I need to encode HTML?
Encoding HTML ensures that browsers display the text exactly as written, rather than executing it as code. This protects against XSS attacks and allows code snippets to be displayed safely.
Is my text sent to a server?
No. All operations run locally in your browser for maximum privacy and performance. Your data never leaves your device.
