About The HTML Encoder and Decoder

The HTML Encoder and Decoder converts special characters such as angle brackets, ampersands, and quotes into HTML entities, then decodes entities back to readable text.

Encoding and decoding run locally in your browser. This tool is useful for inspecting escaped snippets, preparing examples, and avoiding accidental markup rendering.

How to Encode or Decode HTML Entities Online

1. Paste text or an escaped snippet into the Input text box.
2. Click Encode to convert special characters into HTML entities.

Choosing Options Correctly

Encode:
- Use this before displaying user-provided text in an HTML context.
- Use it for documentation snippets that should show markup instead of rendering it.

Decode:
- Use this when reading escaped template output, logs, or API values.
- Decode only trusted text if you plan to render it later.

Common Use Cases

• Escaping code snippets for documentation.
• Inspecting encoded HTML from APIs or templates.
• Converting readable characters to entities for examples.
• Checking why markup is rendering or not rendering.

Quick FAQ

Does encoding make HTML safe everywhere?
No. HTML entity encoding is context-specific. JavaScript, CSS, URL, and attribute contexts need their own escaping rules.

Can I decode full HTML documents?
Yes for entity text, but decoding a document can turn safe-looking text back into active markup if you render it.

Is my text uploaded?
No. Encoding and decoding are designed to run in the browser.

What characters are commonly encoded?
Characters such as ampersand, less-than, greater-than, quotes, and apostrophes are commonly encoded for HTML contexts.
