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 '<').
Operations run locally in your browser, maintaining text privacy.
Encode or Decode HTML Entities
How to Use
Paste Code String
Paste the raw HTML markup or entity-encoded text into the input area.
Run Action
Click 'Encode' to make characters safe for HTML display, or 'Decode' to translate entities back to text.
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 '<div>'. This displays correctly inside a pre tag code block.
Limitations
Converts core character sets. It does not validate HTML syntax errors.
