Web tips

🛡️

Never render user-provided text directly in HTML without encoding. A user could inject <script> tags causing XSS attacks.

🔒

Encoding < as &lt; and > as &gt; turns any HTML tags in user input into plain visible text, not executable markup.

💡

Most server-side frameworks (Django, Rails, Laravel) auto-encode template variables. This tool is for manual encoding or debugging.

🔍

Paste suspicious user input here to inspect what HTML entities it contains before adding it to your codebase or database.
