What people use HTML Encoder for
- Displaying code samples on a web page without the browser executing them as markup.
- Escaping user-supplied text before inserting it into HTML, to prevent cross-site scripting.
- Fixing content that renders as raw tags instead of the characters you intended.
HTML Encoder: limits and things worth knowing
- Five characters carry meaning in HTML and need escaping: < > & " and '. Everything else is optional, and over-escaping is what produces the &amp; double-encoding you see on broken pages.
- Escape the ampersand first. Escaping < to < after you have already escaped & turns it into &lt;, which displays as literal text rather than a tag.
- HTML escaping is context-specific and is not a general XSS defence. Text inside an attribute, inside a <script> block, or inside a URL each need different treatment — entity encoding only protects the HTML text context.
- Numeric entities (<) and named entities (<) are equivalent to a browser; named ones are simply easier to read.
Is it private and secure?
Your privacy is built in. HTML Encoder runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.
Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.
You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
