HTML encoding, also known as HTML escaping, is the process of converting special characters in text to their corresponding HTML entities. This prevents these characters from being interpreted as HTML markup when displayed on web pages. Common characters that require encoding include the less-than symbol (<), greater-than symbol (>), ampersand (&), and quotation marks (").
HTML decoding reverses this process, converting HTML entities back to their original characters. This is essential when you need to display user-generated content safely or when processing data that contains HTML entities. For example, <script> would be decoded back to <script>, but when properly encoded, it displays as text rather than executing as code.
Our tool provides both encoding and decoding capabilities with a live preview feature that safely renders HTML content while protecting against XSS (Cross-Site Scripting) attacks. This makes it invaluable for web developers, content managers, and anyone working with HTML content who needs to ensure safe display and proper character handling.
Cross-Site Scripting (XSS) attacks occur when malicious scripts are injected into web pages. HTML encoding is your first line of defense against these attacks. By converting potentially dangerous characters to HTML entities, you ensure that user input is displayed as text rather than executed as code.
Our tool includes a safe preview feature that sanitizes HTML content before rendering. This allows you to see how your encoded/decoded content will appear while maintaining security. The preview automatically filters out potentially dangerous elements and attributes.
Always encode user input before displaying it on web pages. Use context-appropriate encoding - HTML entity encoding for HTML content, attribute encoding for HTML attributes, and JavaScript encoding for JavaScript contexts. Never trust user input and always validate and sanitize data on both client and server sides.
Safely display user-generated content, debug HTML issues, and ensure proper character encoding in web applications. Essential for preventing XSS attacks and maintaining data integrity in forms and dynamic content.
Handle content migration, clean up imported data with HTML entities, and ensure proper display of special characters in CMS systems. Perfect for managing multilingual content and legacy data conversion.
Create HTML email templates with proper character encoding, ensure special characters display correctly across email clients, and debug rendering issues in email campaigns and newsletters.
Clean and process data exports containing HTML entities, prepare data for import into various systems, and ensure proper character encoding when working with international datasets and special characters.
| Character | HTML Entity | Numeric Code | Description |
|---|---|---|---|
| < | < | < | Less than sign |
| > | > | > | Greater than sign |
| & | & | & | Ampersand |
| " | " | " | Quotation mark |
| ' | ' | ' | Apostrophe |
| |   | Non-breaking space |
Our tool processes HTML encoding and decoding in real-time as you type or paste content. The live preview updates instantly, allowing you to see exactly how your content will appear when rendered on a web page.
The live preview feature safely renders HTML content while protecting against XSS attacks. It sanitizes potentially dangerous elements and attributes, allowing you to see how content will display without security risks.
Easily switch between encoding and decoding modes with the swap function. This allows you to quickly reverse operations and test different scenarios without manually copying and pasting content between fields.
Different contexts require different encoding approaches. Use HTML entity encoding for content within HTML elements, attribute encoding for HTML attributes, and JavaScript encoding when inserting data into JavaScript contexts.
While client-side encoding is useful for display purposes, always perform encoding and validation on the server side as well. Client-side security measures can be bypassed, so server-side protection is essential.
Always test your encoded content in the target environment. Different systems may handle HTML entities differently, so validation in the actual use case ensures proper display and functionality.
Select either Encode to convert special characters to HTML entities, or Decode to convert HTML entities back to readable text. The interface updates automatically based on your selection.
Paste or type your HTML content in the input area. The tool handles large amounts of text efficiently and provides real-time character count and statistics.
Click the process button to encode or decode your content. Use the live preview to see how the result will appear when rendered. Copy the result or swap input/output for reverse processing.
