HTML Entity Encoder Online
Escape text for safe display as HTML text.
Convert characters such as angle brackets and ampersands into HTML entities. Paste the input, make the change, then read the result before you copy it elsewhere.
Context-aware escaping is still required in real applications.
Ready — input is processed locally.
This utility runs on the current device for the supported workflow. Kaazo does not need the pasted input to calculate the result.
HTML Entity Encoder is a narrow tool on purpose
Convert characters such as angle brackets and ampersands into HTML entities.
Entities change representation, not what the browser means
Encoding characters such as <, > or & can make text safe to represent inside HTML text contexts. It isn’t a complete defence for every HTML, attribute, URL or script context.
Context matters. HTML-text escaping is not a substitute for the correct escaping rules inside JavaScript, CSS or URLs.
Where HTML Entity Encoder fits cleanly
Show HTML code as text. Escape simple content for examples. Both jobs fit because they ask the tool to do exactly what its output is designed for, without adding an unrelated conversion.
When HTML Entity Encoder isn’t the right endpoint
Use context-aware escaping or sanitisation in application code when handling untrusted user input.

Does formatted or converted output prove the data is valid for my application?
No. HTML Entity Encoder can perform the syntax or data operation described here, but your application can still impose its own schema, business rules, encoding or security requirements.
