HTML Entity Encoder/Decoder

Safely encode HTML entities to prevent XSS attacks, or decode raw entities back to standard characters online.

About HTML Entity Encoder / Decoder

Our HTML Entity Encoder / Decoder is a specialized security and development utility for webmasters who need to handle reserved characters safely within HTML source code. Encoding characters like `<` and `&` into their entity equivalents (like `<` and `&`) is the primary defense against Cross-Site Scripting (XSS) attacks and ensures that code snippets render correctly as text rather than being interpreted as markup by the browser.

This tool is indispensable for educational bloggers, forum moderators, and developers documenting technical work who need to display raw HTML tags clearly on a live webpage.

Security & Display Features

  • XSS Prevention: Safely sanitize user-generated content or raw code before rendering it in a browser view.
  • Named & Numeric Support: Correctly encodes both standard named entities and complex Unicode numeric references.
  • Batch Processing: Seamlessly handle massive blocks of markup without losing character fidelity.

Quick Setup Instructions

  1. Paste your raw HTML or encoded entities into the transformation area.
  2. Click 'Encode' to secure your markup or 'Decode' to return entities to readable text.
  3. Copy the result and paste it directly into your CMS, forum post, or source file.

Pro Tip

When writing coding tutorials, always encode your sample tags so the browser displays the code itself rather than trying to execute the formatting.
