β Frequently Asked Questions
What is HTML sanitization?
HTML sanitization is the process of removing or escaping potentially malicious content from HTML code, such as script tags, event handlers, and iframes. It is a critical security measure to prevent XSS (Cross-Site Scripting) attacks.
What's the difference between Strip and Escape modes?
Strip mode directly removes dangerous elements and attributes. Escape mode preserves content but escapes special characters into HTML entities, making scripts non-executable while keeping text visible. Report Only lists security issues without modifying the HTML.
What should I remove?
At minimum, we recommend removing script tags, inline event handlers (like onclick), and iframes. If you allow user-submitted HTML content (comments, forum posts), enable all security options.
Can this replace server-side validation?
No. This is a helper tool to preview and clean HTML before inserting into a database. Actual protection must rely on server-side validation and output encoding.
