When the result looks wrong
Entity encoding is not a complete HTML sanitizer or XSS protection strategy.
Questions about HTML Entities
Is my input uploaded?
File and text processing runs in your browser. Opening the website still loads application assets from its host.
What if the result looks wrong?
Entity encoding is not a complete HTML sanitizer or XSS protection strategy.
Can I use sensitive production data?
Prefer non-sensitive test data. Never paste live access tokens, passwords or confidential documents into a site without assessing its code and environment.
