Encode or decode HTML entities for safe web use

HTML Encoder / Decoder — Escape and Unescape HTML Entities for Web Development

  1. Paste your HTML code or text containing special characters. Common characters that need encoding include <, >, &, ", and ' — plus any Unicode characters you want represented as HTML entities.
  2. Click Encode to convert special characters to their HTML entity equivalents (< → <, > → >, & → &, " → ", ' → '). Click Decode to reverse the process. The tool handles both named entities and numeric (decimal/hex) character references.
  3. Copy the encoded HTML for safe embedding in web pages, email templates, or code examples. Proper encoding prevents XSS attacks, rendering issues, and broken HTML markup.

Frequently Asked Questions

Is the HTML Encoder free?

Yes, completely free. Use it for development, content management, email template creation, or any HTML-related task with no limits.

Are my HTML code or data uploaded anywhere?

No. All encoding and decoding happens locally in your browser. Your code never leaves your device, ensuring proprietary source code and content remain secure.

Why is HTML encoding important and when should I use it?

HTML encoding (also called HTML escaping) is critical for web security and correct rendering: (1) Security — it prevents Cross-Site Scripting (XSS) attacks by neutralizing <script> tags and event handlers that malicious users might inject into comment sections, forums, or user profiles. (2) Correct rendering — if your content contains < or > symbols (common in code snippets, math expressions like "x < 5", or XML examples), browsers will interpret them as HTML tags unless encoded. (3) Email HTML — email templates require entities for special characters to display correctly across different email clients. (4) Code documentation — when displaying HTML/XML source code on a web page, encode it so the browser renders the code as text rather than executing it. Always encode user-generated content before displaying it on a web page.
