How to Use HTML Entity Encoder Online: Step-by-Step Guide
Escape special characters into HTML entities (<, >, &, ") to prevent XSS vulnerabilities
About HTML Entity Encoder — Free Online Tool
HTML Entity Encoder replaces the five characters that let text break out of markup with their entity equivalents.
Exactly five substitutions are made in one pass: & becomes &, < and > become < and >, the double quote becomes " and the apostrophe becomes '. Everything else is left as literal UTF-8 — accented letters, curly quotes and emoji are not converted to numeric references, which is correct for any page that declares a UTF-8 charset. Because the pass is unconditional, text that already contains entities is escaped a second time: an existing & comes back as &amp;, so encode raw text rather than the output of an earlier encode.
The substitution runs in your browser and the text is not sent to a server.
Showing a code sample on a page without the browser running it, putting a snippet inside a template attribute, escaping user-supplied text before it is written into markup, and quoting an HTML fragment in documentation.
