How to use the HTML encoder

  1. Paste the text, markup or code you want to display.
  2. Choose which characters to encode (the defaults cover all five HTML-special characters).
  3. Click Encode and paste the result into your page - it renders as text, never markup.

Frequently asked questions

Why HTML-encode at all?

Without escaping, characters like "<" and "&" can be parsed as markup, breaking layouts or, in the worst case, letting injected scripts run (XSS). Escaped output renders literally.

Which characters are encoded?

& becomes &, < becomes <, > becomes >, " becomes " and ' becomes '. All five by default.

Is encoding the same as sanitizing?

Not quite. Encoding is deterministic and preserves your text; sanitizing removes or rewrites content to neutralize scripts. Both have a place - encoding is the safe default for displaying text.

Does it work for attributes?

Yes - encoding quotes is exactly what makes text safe inside HTML attributes like title="...".

Is the encoder free and offline?

Yes, it runs locally in your browser with no server involved.

Why is HTML encoding important for web security?

HTML encoding prevents Cross-Site Scripting (XSS) attacks by ensuring that user-provided text cannot be interpreted as executable HTML tags or scripts by the browser.

What does &quot; and &#39; represent?

" represents double quotes (") and ' represents single quotes ('), allowing values to be placed safely inside HTML attribute quotes.

Should I encode text before storing it in a database or before displaying it?

Best practice is to store raw input and encode it at the moment of rendering into an HTML context.
