About HTML Encode Online:

HTML encoding (also known as HTML escaping) is the process of replacing special characters with their corresponding HTML entities. For example, the less-than sign < becomes &lt;, the ampersand & becomes &amp;, and double quotes " become &quot;.

This is essential when displaying user-generated content on web pages. Without proper encoding, browsers may interpret special characters as HTML markup, which can break the page layout or, worse, create cross-site scripting (XSS) vulnerabilities that attackers can exploit.

This tool encodes all five critical HTML characters: & (ampersand), < (less-than), > (greater-than), " (double quote), and ' (single quote / apostrophe). The decode function reverses the process, converting HTML entities back to their original characters. All processing happens entirely in your browser.
