How to use the HTML encoder
- Paste the text, markup or code you want to display.
- Choose which characters to encode (the defaults cover all five HTML-special characters).
- 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 " and ' 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.
