The HTML Entity Encoder Decoder helps developers format characters for safe HTML parsing. Special characters (like '<', '>', or '&') have syntax meanings in HTML. If you display these symbols literally inside code examples, the browser parses them as actual tags, breaking rendering. Encoding converts these to safe entities (like '&lt;').

Operations run locally in your browser, maintaining text privacy.

Encode or Decode HTML Entities

How to Use

1

Paste Code String

Paste the raw HTML markup or entity-encoded text into the input area.

2

Run Action

Click 'Encode' to make characters safe for HTML display, or 'Decode' to translate entities back to text.

3

Copy Output

Copy the converted string to use in your code editor or CMS page template.

Why This Tool Is Useful

Safe Code Display: Display HTML tags as code blocks on pages without breaking layout rendering.

Prevent XSS injection: Encode input data fields to block malicious script tags from running.

100% Client-Side: Safely encode code snippets locally without external server logs.

Practical Example

A developer writes a tutorial showing a div tag: '<div>'. Paste it in the tool, select 'Encode', and get '&lt;div&gt;'. This displays correctly inside a pre tag code block.

Limitations

Converts core character sets. It does not validate HTML syntax errors.

FAQ

What are HTML entities?
HTML entities are strings that represent reserved characters (like '<') or characters that are hard to type (like '©').
Why do I need to encode '<' and '>'?
Browsers treat '<' and '>' as tag markers. If you want to show literal code examples, you must encode them so they render on screen.
What is a named entity vs a numeric entity?
Named entities use abbreviations (like '&amp;'), while numeric entities use numbers (like '&#38;'). Both display identically.
Does the tool store my code?
No, formatting is executed locally inside your browser memory using JavaScript.
Does it support accented characters?
Yes. Accents and special symbols (like currency symbols) encode and decode correctly.
