HTML Entity Encoder & Decoder

Encoding prevents text from being interpreted as markup, which avoids broken layouts and cross-site scripting (XSS) when handling user input.

We encode the five reserved characters: & " and '. These are the ones that can break or inject into HTML.

No. Accented letters (é, ü) are left as-is because modern UTF-8 pages handle them natively.

Encode — converts < > & " ' into safe entities. Perfect before inserting user input into HTML.
Decode — turns entities like < back into their literal characters.
Copy the result straight to your code or template.
