What is the HTML Entities Encoder Decoder?
The HTML Entities Encoder Decoder is a free online tool that converts special characters to their corresponding HTML entity representations and vice versa. HTML entities are used to display reserved characters in HTML that would otherwise be interpreted as code, such as <, >, &, and quotes.
This tool supports both named entities (like & for &) and numeric entities (like < for <). It handles all Unicode characters, making it perfect for international content and special symbols. The tool operates entirely in your browser, ensuring fast processing and complete privacy of your data.
Why Use This HTML Entities Tool?
Prevent XSS Attacks: Properly encode user input and dynamic content to prevent cross-site scripting (XSS) vulnerabilities in your web applications.
Display Special Characters: Correctly display reserved HTML characters like <, >, &, and quotes in your web content without breaking your HTML structure.
Unicode Support: Encode and decode all Unicode characters, making it easy to work with international text, emojis, and special symbols in HTML.
Instant Processing: Convert text instantly with real-time encoding and decoding. No waiting, no server requests - everything happens in your browser.
Developer Friendly: Essential tool for web developers working with HTML, XML, or any markup language that uses entity encoding.
Common Use Cases
Web Development: Encode special characters in HTML content, attributes, and JavaScript strings to ensure proper rendering and prevent syntax errors.
Content Security: Sanitize user-generated content by encoding HTML entities before displaying it on web pages, protecting against XSS attacks.
Email Templates: Encode special characters in HTML email templates to ensure they display correctly across different email clients.
Database Content: Decode HTML entities from database content that was stored in encoded format for proper display in applications.
API Development: Encode or decode HTML entities when working with APIs that send or receive HTML content, ensuring data integrity.
XML Processing: Convert special characters to entities for valid XML documents, or decode entities when parsing XML data.
How to Use the HTML Entities Encoder Decoder
To Encode Text: Paste or type your text containing special characters into the input field. Click the Encode button to convert all special characters to their HTML entity equivalents. For example, '<div>' becomes '<div>'. Copy the encoded text and use it in your HTML documents.
To Decode Entities: Paste HTML code containing entities (like &, <, >) into the input field. Click the Decode button to convert all HTML entities back to their original characters. The decoded text will show the actual characters instead of entity codes.
Tips for Best Results: The tool automatically detects both named entities (&) and numeric entities (&). You can encode entire HTML snippets at once. Use encoding when inserting dynamic content into HTML to prevent code injection. Always validate your encoded output in your target environment to ensure compatibility.
