HTML Encoder/Decoder
Encode or decode HTML entities in your text.
About HTML Encoder/Decoder
For developers, bloggers and email template builders, the HTML Encoder/Decoder turns minutes of manual working into an instant, clearly labelled result. Being browser-based and offline-capable, it is safe for sensitive values: nothing you type is transmitted or stored anywhere but your own machine. Encode and decode HTML entities so special characters like angle brackets, ampersands and quotes are shown literally instead of being parsed as markup. The tool converts less-than to amp-l-t-semicolon and back, which is how code snippets are shown on a page and how user input is made safe from injection. Developers use it to embed code in a post, bloggers to show HTML examples, and because everything runs locally, nothing is uploaded. The tool handles both named and numeric entities and works on full blocks. It is the HTML entity tool that pasting code into a page always needs. You will find it handy when showing an HTML code snippet on a page, while escaping user input to prevent injection, or before encoding an email template special character. Try it the next time a quick decision needs real numbers behind it.

Why encode HTML entities?
Encoding prevents angle brackets and ampersands from being parsed as markup, which shows code literally and stops injection.
