Free Online HTML Entity Encoder & Decoder

Encode special characters to secure HTML entities or decode safe entities back to plain text.

How to use & benefits of HTML Entity Encoder/Decoder

Secure and Sanitize Web Text Inputs

HTML uses specific characters (like < and >) to define markup tags. If you want to display these characters inside a browser instead of parsing them as code, they must be converted into HTML Entities (like < and >). This process is crucial to prevent Cross-Site Scripting (XSS) attacks.

Our free online HTML entity encoder and decoder sanitizes strings instantly:

HTML Encoding: Replaces <, >, &, ", \' and non-ASCII characters with entities.
HTML Decoding: Restores entities back to normal symbols.

The utility runs locally, ensuring code snippets stay private.
