What Is HTML Decode?

HTML Decode is the process of converting encoded HTML entities back into their original readable characters.

For example:

Encoded HTML:

<h1>Hello World</h1>

After HTML Decode:

<h1>Hello World</h1>

The decoder transforms special HTML entities into normal text characters.

Why HTML Encoding Exists

Before understanding decoding HTML, you must first understand HTML encoding.

Web browsers interpret certain characters as HTML instructions.

For example:

If these characters appear as normal text, browsers may misinterpret them.

That is why they get encoded into HTML entities.

Example:

< → &lt;
> → &gt;
& → &amp;
" → &quot;

HTML decoding reverses this process.

What Is an HTML Decoder?

An HTML decoder is a tool or function that converts encoded HTML entities into readable text.

Example:

Input:

Tom & Jerry
