🏷️ HTML Encoder / Decoder
HTML Encoder/Decoder escapes the five characters that break HTML — & < > ' " — into their entities (& < > ' ") and decodes them back, live as you type. Unicode characters pass through untouched; only the five reserved characters are affected. It runs entirely in your browser and never sends your text anywhere.

| Reading an email source snippet | Decode | Entities become readable characters |
| Fixing & in copied titles | Decode | Restores the original characters |
| Emoji and accented letters | Nothing needed | Unicode is preserved as-is |
| Escaping for URLs | Wrong tool | Use URL Encoder instead |

Detailed User Guide
Encode HTML to display code as text
Encoding converts characters like < and > into entities such as < and >, so a code snippet shows up as literal text on a page instead of being rendered as markup.
Decode entities back to characters
Decoding does the reverse, turning & back into & and other entities into their original characters — handy when reading escaped content.
Protects against injection in templates
Encoding untrusted text before injecting it into HTML is a basic defense against XSS and broken layouts, which is why this tool is a common companion to web development.
Local processing, no uploads
Everything happens in your browser, so sensitive content or proprietary code never leaves your device.
Handles the full entity set
Common named entities and numeric references are both covered, so content pasted from CMS exports or emails decodes cleanly.
Common use: embedding code in tutorials
When you write a tutorial or blog post that shows HTML examples, encoding the snippet first prevents the browser from rendering it and keeps your example visible as text.
Numeric vs named entities
The encoder supports both named entities like & and numeric references like &, so you can pick the style your project or CMS expects when escaping content.
