Frequently asked questions

What are HTML entities?

HTML entities are codes that represent characters with special meaning or that are hard to type in HTML. They start with & and end with a semicolon, such as &lt; for <, &amp; for & and &copy; for the copyright sign. Numeric forms like &#169; also work.

How do I escape HTML special characters?

Paste the text in Encode mode. The five characters & < > " and ' are replaced with &amp; &lt; &gt; &quot; and &#39;. For example, <p>Fish & Chips</p> becomes &lt;p&gt;Fish &amp; Chips&lt;/p&gt;, which browsers show as text instead of running it as markup.

How do I decode HTML entities back to text?

Switch to Decode and paste the text. Named entities such as &amp; and &copy;, and numeric ones like &#233; or &#xE9;, are converted to real characters. Only a common set of named entities is recognised, so a rare name may stay as is.

What does Encode non-ASCII characters do?

When it is on, every character above code point 126 is written as a numeric entity, so é becomes &#233; and the pound sign becomes &#163;. This is useful for systems that cannot handle UTF-8. When it is off, those characters are left as they are.

Does escaping HTML prevent XSS attacks?

Escaping user input before inserting it into HTML text is a core defence against cross-site scripting, but context matters. Attributes, URLs, JavaScript and CSS need their own escaping rules. Use your framework built-in escaping instead of doing it by hand where possible.

What is the difference between &nbsp; and a normal space?

A non-breaking space (&nbsp;) looks like a space but stops a line from wrapping there, and browsers do not collapse several of them into one. A normal space can be collapsed and wrapped. On decoding, this tool turns &nbsp; into a regular space character.

Is my data shared when using the HTML Entity Encoder/Decoder?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the HTML Entity Encoder/Decoder?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.

Is it safe to paste API tokens or private JSON data here?

Yes, absolutely. The tool executes 100% inside your local browser memory space. No inputs are sent to any servers.
