HTML Entity Encoder: Safely Display HTML in Web Content

Instantly convert special characters (<, >, &, ", ') in your text to HTML entities. Protect your website from XSS, display code safely in blogs, and ensure user input won't break your layout. Paste or type your HTML/code below—get clean, encoded output for secure web publishing.

Special characters will be converted—no code will be executed or displayed as HTML.
Why encode?
Use this tool to display code safely in tutorials, blogs, comments, and to sanitize user input in web forms.

How to Encode HTML Entities for Safe Web Display

  1. Paste or type your text, HTML, or code snippet into the left box above.
  2. Click Encode to convert special characters (<, >, &, ", ') into their HTML entity equivalents.
  3. Copy the encoded output and use it in your website, blog, CMS, or email where you want the raw code to display safely, not execute.

This process ensures your text is displayed as intended—no HTML will run or break your page layout. Essential for secure code sharing and user-generated content.

Where Should You Encode HTML Entities?

User Comments & Forums

Prevent users from injecting harmful code—encode all user-submitted content before displaying it on your site.

Embedding Code Samples

Show code safely in blogs, documentation, and tutorials—encode so it displays as text, not as rendered HTML.

Preventing XSS Attacks

Sanitize form input and database content to stop malicious scripts. HTML entity encoding is a core defense against XSS.

Email & RSS Feeds

Encode HTML in email templates and feeds to avoid accidental rendering of code or breaking client layouts.

CMS & Website Builders

When adding custom HTML to your CMS, encode entities to prevent site editors from corrupting pages with unescaped code.

API Responses & Logs

Encode HTML in API responses or logs to ensure safe rendering in dashboards or viewers that support HTML content.

Common Mistakes in HTML Entity Encoding

  • Double encoding: Encoding already-encoded text results in unreadable gibberish. Only encode once, just before output.
  • Forgetting to encode user input: Failure to encode lets attackers inject scripts or break your page.
  • Encoding at the wrong stage: Always encode on output, not when saving to your database.
  • Not encoding in emails or feeds: HTML in these contexts can render unexpectedly or break formatting.

Code Example: Before & After

Before: <script>alert('XSS!')</script>
After Encoding: &lt;script&gt;alert(&#39;XSS!&#39;)&lt;/script&gt;
Encoded output is safe to display—browsers show the code, not execute it.
Tip: Test your output by pasting it into your website or CMS preview to ensure it displays as plain text and not as rendered HTML.

Practical Examples: Secure HTML Display

Blog Comment (Unencoded)
Hello <b>everyone</b>! Visit <a href="https://minitweak.com">my site</a>.
Blog Comment (Encoded)
Hello &lt;b&gt;everyone&lt;/b&gt;! Visit &lt;a href="https://minitweak.com"&gt;my site&lt;/a&gt;.
Form Field (Unencoded)
Form Field (Encoded)
<input type="text" value="&lt;h1&gt;Welcome!&lt;/h1&gt;" />
HTML escape vs encode: Both terms refer to turning special characters into their HTML-safe entity equivalents. Always use encoding before displaying raw code or user input in HTML.

Frequently Asked Questions (FAQ)

HTML entity encoding converts special characters (like <, >, &, ", ') into HTML-safe representations (e.g., &lt;, &gt;, &amp;, &quot;, &#39;). This prevents browsers from interpreting them as code, ensuring they're displayed as plain text. It's essential for web security and data integrity—without encoding, attackers can inject scripts (XSS) or break your site's layout.

Double encoding (encoding already-encoded text), forgetting to encode user-generated content, or encoding at the wrong stage (e.g., when saving to the database instead of on output) are common mistakes. These can lead to garbled text, broken layouts, or security vulnerabilities. Always encode once, right before displaying the content in HTML.

Only encode values in JSON or API responses if that data will be inserted into HTML content. Raw JSON used in JavaScript or data storage does not need entity encoding. However, if you output JSON into a web page (e.g., via <script> tags), encode it to prevent XSS or rendering issues.

In this context, escaping and encoding mean the same thing—replacing special characters with their HTML-safe entity equivalents so browsers display them as text. The terms are often used interchangeably for web security and safe code display.

Use our HTML Entity Decoder tool to convert encoded entities (like &lt;, &gt;, &#39;) back to their readable characters. This is useful when copying content from HTML back to plain text or when processing imported data.
