Does this protect against all forms of XSS?

HTML-encoding text before displaying it in HTML content is one important defense, but full protection depends on context (attributes, scripts, URLs) and should follow established security guidance.

Why is the apostrophe encoded as ' instead of '?

' is universally supported across all HTML versions, while ' is not valid in older HTML specifications.

Does this encode every character, or just five?

Just the five characters with special meaning in HTML: & " ' — normal letters and numbers are left unchanged.

Is my text uploaded anywhere?

No — encoding happens entirely in your browser.

Can I encode a whole HTML document with this?

Yes, though encoding an entire document will also escape its actual tags — this tool is best used on plain text or specific values, not full markup you want to keep intact.

Will encoded text display correctly in a browser?

Yes — when placed back into HTML, the encoded entities render as the original characters exactly as typed.

What Is HTML Encoding?

HTML encoding replaces characters that have special meaning in HTML — &, <, >, " and ' — with their corresponding entity codes (&, <, >, ", '), so that text containing those characters displays correctly instead of being misinterpreted as markup.

This matters whenever raw text (like a username, comment, or code snippet) needs to be safely displayed inside an HTML page without accidentally being parsed as tags or breaking the page's structure.

Always encode untrusted text before displaying it inside HTML to prevent markup injection.

Use for Code Snippets in Articles

Encode code samples containing < and > so they display literally instead of as tags.
