HTML Encoder/Decoder

Convert characters to HTML entities to prevent rendering bugs, and decode them.

How to Use HTML Encoder/Decoder

  1. Paste raw text with special characters (like `<`, `>`, `&`) into the "Encode" box to convert them into safe HTML entities.
  2. Paste entity-encoded text (like `&amp;lt;`) into the "Decode" box to get the original characters back.
  3. Copy the converted result for use in your markup or documentation.

Key Features & Practical Use Cases

  • Converting unsafe characters into secure HTML entities to prevent XSS injection attacks.
  • Decoding scraped HTML entities back into standard text for data processing.
  • Escaping code blocks safely so they render visually on web pages without executing.

Frequently Asked Questions

Why would I need to encode HTML entities?

It lets you display code snippets or special characters (like `<div>`) as visible text on a web page instead of having the browser try to render them as actual HTML.

Does this replace a proper sanitization library for user input?

No - for sanitizing untrusted user input in a real application, use a dedicated library (like DOMPurify); this tool is for quick manual encode/decode tasks.

Does it handle named entities like `&nbsp;` as well as numeric ones?

Yes, both common named entities and numeric character references are decoded correctly.
