Frequently Asked Questions

What is an HTML entity encoder used for?

An HTML entity encoder converts special characters like <, >, and & into their respective HTML code formats (such as &lt;). This ensures browsers display text correctly and prevents code injection attacks.

How do I decode HTML entities?

Simply paste your text containing HTML entities into the tool and click the 'Decode' button. The tool will instantly translate the entity codes back into their original, readable characters.

Why do I need to encode special characters in HTML?

If you use characters like angle brackets (< >) without encoding them, the browser will interpret them as HTML tags. Encoding ensures these characters are displayed as visual text on your webpage rather than executed as code.

Is this HTML entity encoder free to use?

Yes, this tool is completely free to use with no hidden costs or usage limits. You can encode and decode as much text as you need without requiring an account.

Does this tool store my converted text?

No, your privacy is completely protected. All encoding and decoding happens directly in your web browser, meaning your data is never uploaded to or stored on any external servers.
