HTML Encoder & Decoder Online - Render and Secure HTML Codes Safely
HTML Encoder & Decoder is a powerful web utility that helps developers, designers, and bloggers encode special characters (like angle brackets, quotes, and ampersands) into their corresponding HTML entities. This prevents web browsers from interpreting them as executable markup code, allowing you to display code snippets safely and protect applications against Cross-Site Scripting (XSS) vulnerabilities.
Key Features
- 100% Client-Side Privacy: All conversions are computed strictly in your browser via local JavaScript. No code or private input is transmitted over the web.
- Flexible Output: Toggle between simple Named Entities or a complete conversion of all special and non-ASCII characters into decimal numbers.
- Accurate Decoding: Native browser-level DOM parser quickly converts decimal, hexadecimal, or named entities back into their raw format.

Frequently Asked Questions (FAQs)
Why should I encode HTML code?
Encoding is necessary when you want to display HTML tags as literal text on a webpage instead of letting the browser render them as live code. It also sanitizes user inputs by neutralizing potential script tags.
What is the difference between Named and Full entity modes?
Named mode only encodes a small subset of special characters that affect HTML structure, such as &, <, >, ", '. Full mode converts all special and non-ASCII characters into numeric entities (Decimal codes), ensuring maximum security and compatibility across various environments.
