What problem does this tool solve?

Some characters have structural meaning in HTML. This entity converter helps display those characters as text and makes supported encoded character references readable again.

Six practical questions answered

How can I display HTML code as plain text on a web page?

Encode HTML special characters, particularly <, >, and &, as character references. Add the escaped result to an appropriate text context rather than treating the original source as active markup.

How do I turn &amp; back into an ampersand?

Choose Decode. The named reference &amp; becomes the & character in the plain-text result.

How do I encode quotation marks for HTML?

Choose Encode. The converter replaces double and single quotation marks with corresponding character references, along with &, <, and >.

Why do HTML special characters sometimes display incorrectly?

Common causes include incorrect character encoding, double entity encoding, or decoding in the wrong context. Inspect the actual input before applying another encoding step.

How can I prepare an HTML example for a blog tutorial?

Encode the special characters so the example is displayed as source text. Check the publishing system as well, since some editors automatically escape code blocks.

How do I decode a passage containing many HTML entities?

Paste it and choose Decode. Supported named and numeric character references are replaced with ordinary characters. The output is displayed as text, never inserted as executable markup.

Practical example

A blogger wants to show a link’s HTML source in a tutorial. They encode its special characters so readers can see the code instead of the browser rendering it as a clickable link.

How to use the tool

Paste text and choose encoding or decoding. Output is displayed only as text and can be downloaded.

Additional use cases

  • Prepare an HTML example for documentation.
  • Read named entities in copied text.
  • Escape quotes for a controlled HTML context.

Limits and supported formats

This is not a general HTML sanitizer. Do not insert decoded content into executable HTML without appropriate validation.

Frequently asked questions

What is an HTML entity?

In this context, it is a character reference used to represent a character in HTML, such as &amp; or &#169;.

Can I convert HTML entities for free?

Yes. This converter is free and does not require registration.

Are numeric HTML references supported?

Yes. Supported decimal and hexadecimal numeric character references can be decoded, such as &#169; and &#xA9;.

Does HTML encoding fully protect a website from XSS?
