คำถามที่พบบ่อย

›Why do I need to escape HTML?

To prevent special characters from being interpreted as HTML tags. < becomes &lt; so the browser shows the character instead of opening a tag.

›What characters need escaping?

At minimum: < > & " '. For maximum safety, escape every non-ASCII character to numeric entities like &#x1F600;.

›Is my input uploaded?

No — runs entirely in your browser.

›Does it handle named entities like &copy;?

Yes — both named (&copy;) and numeric (&#169; or &#xA9;) entities are decoded correctly.

›Is the tool free?

Yes — fully free, no signup.
