Free HTML Encoder and Decoder Online

Need to display HTML code on a webpage without it being rendered as markup? Or decode HTML entities in content you've received? Convertly.ng's free HTML Encoder/Decoder converts special characters to HTML entities and back — instantly, in your browser, no setup needed.

What Is HTML Encoding and Why Does It Matter?

HTML encoding converts special characters (like <, >, &, ") into HTML entities (&lt;, &gt;, &amp;, &quot;) so they can be safely displayed in a webpage without being interpreted as HTML code. This is essential for displaying code snippets, preventing Cross-Site Scripting (XSS) attacks, and handling user-generated content safely.

When Do You Need an HTML Encoder?

  • Display code on a webpage — Encode HTML/JavaScript snippets before showing them on a blog or documentation site
  • Email templates — Properly encode special characters in HTML email content
  • Form data processing — Encode user input before storing or displaying it
  • API responses — Decode HTML-encoded content returned by APIs
  • Content management systems — Understand and convert encoded content from CMS exports
  • Web security — Sanitise content to prevent XSS vulnerabilities

🔐 Common HTML Entities

&lt; = < (less than) | &gt; = > (greater than) | &amp; = & (ampersand) | &quot; = " (double quote) | &apos; = ' (apostrophe) | &nbsp; = non-breaking space. These are the most commonly encoded characters in web development.

Encode vs Decode — Which Do You Need?

Encode — You have raw text with special characters and need HTML-safe entities. Use this before inserting user input into HTML or displaying code on a page.

Decode — You have HTML entity text (e.g. &amp; &lt;) and need the original characters back. Use this to read API responses or CMS exports that contain encoded HTML.

Frequently Asked Questions

Is HTML encoding the same as URL encoding?

No — they're different. HTML encoding converts characters to HTML entities (&lt;, &amp;, etc.). URL encoding converts characters to percent-encoded format (%3C, %26, etc.) for use in URLs. Both serve different purposes.

Will it encode all special characters?

Yes — all standard HTML special characters including angle brackets, ampersands, quotes, and extended Unicode characters can be encoded.

Is the HTML Encoder free?

Yes — completely free with no account required.

Does my data get stored on your servers?

No — encoding and decoding runs entirely in your browser. No data is uploaded or stored.
