What is HTML Encoding?

HTML encoding converts reserved or special characters into HTML entities so they can safely appear as text inside HTML documents instead of being interpreted as markup.

For example, the less-than character < becomes &lt;, while & becomes &amp;.

Other common examples include > → &gt; and " → &quot;.

What is HTML Decoding?

HTML decoding converts HTML entities back into their original readable characters. It is useful when content has previously been encoded and you need to inspect or reuse the original text.

For example, &lt; becomes <, and &amp; becomes &.

This decoder also supports decimal and hexadecimal numeric entities such as &#60; and &#x3C;.

When Should You Use an HTML Encoder?

An HTML encoder is especially useful when HTML code or special characters need to be shown as text rather than interpreted by a browser.

  • Displaying HTML code as text
  • Preparing snippets for documentation
  • Preventing markup from being interpreted as HTML
  • Working with user-generated content
  • Debugging encoded content
  • Preparing HTML for certain data formats

When Should You Use an HTML Decoder?

Use an HTML decoder when you receive content containing HTML entities and need to restore the original characters for reading, editing, troubleshooting or further processing.

  • Reading encoded HTML snippets
  • Inspecting entity-encoded content
  • Cleaning copied HTML text
  • Debugging entity conversion issues
  • Restoring readable text from encoded data

HTML Encoding Example

HTML encoding changes reserved characters into entities while keeping the original content safe to display as text.

Original
<div>Hello & welcome</div>
Encoded
&lt;div&gt;Hello &amp; welcome&lt;/div&gt;
Encoded
&lt;p&gt;Welcome to NameUpWeb&lt;/p&gt;
Decoded
<p>Welcome to NameUpWeb</p>
Your text stays in your browser. This tool processes HTML locally and does not upload your content to our servers.
