HTML Entity Encoder

Encode/decode HTML entities and escape special characters.

Plain Text

Encoded Output

&lt;a href=&quot;/page?x=1&amp;y=2&quot;&gt;Tom &amp; &quot;Jerry&quot;&lt;/a&gt;

How it works

Encoding makes text safe to display as literal characters; it is not a security sanitizer for untrusted HTML.
It converts standard named and numeric entities; unusual custom entities may not be recognized.

When you want characters like <, >, and & to appear literally on a page instead of being interpreted as markup, for example showing code samples.

It helps text display literally, but it is not a full XSS sanitizer. For untrusted HTML, use a dedicated sanitizer in your app.

No. Encoding and decoding are instant and local in your browser.
