HTML Entity Encoder

What is the HTML Entity Encoder?

Escape special characters into HTML entities. Encoding special characters as HTML entities lets you show code and symbols on a web page without the browser treating them as markup.

How to use the HTML Entity Encoder

1. Paste or type your your text into the box (a sample is pre-filled so you can see how it works).
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: result.
4. Use the 📊 chart to see the result visually, then copy or share it.

Where the HTML Entity Encoder helps in real life

You are writing a tutorial and want to show the snippet <div class="box"> on the page. Encoding it turns the angle brackets into entities so readers see the code instead of an empty box.

A developer displays user-submitted comments and wants to understand how escaping protects the page from injected HTML.

Common mistakes to avoid

• Encoding text twice, so readers see &amp;amp; on the page.
• Relying on manual encoding instead of your framework’s escaping.
• Forgetting to encode quotes inside attribute values.
• Encoding content that should render as real HTML.

💡 Practical tip: Escaping user input before showing it on a page is one of the basic defenses against cross-site scripting.

Tips for better results

• Let your template engine escape output automatically where possible.
• Encode code samples before placing them inside pre or code tags.
• Preview the page to confirm the code displays correctly.
