How to use HTML Entity Encoder / Decoder
HTML entities let reserved markup characters appear as text. The encoder protects ampersands, angle brackets and quotes, while the decoder turns named or numeric entities back into readable characters.
Entity encoding is context-specific. Escaping text for an HTML text node is not automatically sufficient for JavaScript, CSS, URL or every attribute context.
A reliable workflow
- Choose Encode or Decode
- Paste the exact text fragment rather than an entire untrusted document
- Review the result in the destination context before rendering
Worked example
Encode the included button markup as displayable text
<button aria-label="Save & close">Done</button>Angle brackets, the ampersand and quotes become entities instead of active markup. This text-node encoding does not replace contextual sanitization for arbitrary HTML
When this tool helps
- Show a code fragment inside documentation
- Decode copied CMS or feed text
- Prepare a literal ampersand or angle bracket for HTML text
Accuracy and safety notes
- Use framework escaping and trusted sanitizers when rendering untrusted HTML
- Encoding does not make arbitrary markup safe to execute
Frequently asked questions
Does XXF upload or store my data?+
No. The conversion runs locally in your browser. Your input is not sent to XXF, stored on a server or used for training.
Which characters are encoded?+
The encoder protects ampersands, angle brackets, double quotes and single quotes—the characters most commonly unsafe in HTML text.
