How to Convert Text to HTML Entities Online

Paste your text and all HTML-sensitive characters (&, <, >, ", ') are converted to their entity equivalents (&amp;amp;, &amp;lt;, etc.). This makes the text safe for embedding in HTML documents without being interpreted as markup.

Why Use HTML Encode Online?

Displaying user-generated content on web pages requires HTML encoding to prevent cross-site scripting (XSS) attacks and rendering issues. If you embed raw text containing < or > into HTML, the browser will interpret it as tags. Encoding converts these to safe entity references.

Frequently Asked Questions

What characters need HTML encoding? The five critical characters are: & (&amp;amp;), < (&amp;lt;), > (&amp;gt;), " (&amp;quot;), and ' (&amp;#39;). These have special meaning in HTML.

Does this prevent XSS attacks? Encoding output is one layer of XSS prevention. It prevents injected scripts from executing by converting < and > to entities. Always combine with other security practices.
