DEV 🔐 Encoding

HTML Encoder / Decoder

HTML encoding converts special characters into their corresponding HTML entities. This is critical for preventing Cross-Site Scripting (XSS) attacks by ensuring user input is rendered as text rather than executed as markup.

How to Use

  1. Select Encode to convert HTML characters to entities, or Decode to convert entities back.
  2. Paste your HTML or text into the input panel.
  3. Click Transform to encode or decode.
  4. Encoded output is safe to embed in HTML without risk of script execution.

How It Works

The tool uses the browser's DOM API: innerText → innerHTML for encoding (HTML entities are inserted), and innerHTML → innerText for decoding (entities are resolved). This handles all standard entities: & < > " ' and their numeric equivalents.
