Frequently Asked Questions
Why do I need to encode HTML?
If you display user-submitted text directly in HTML, characters like < and > will be interpreted as tags, breaking your layout or creating XSS security vulnerabilities. Encoding converts them to safe entities.
What are the most common HTML entities?
The most important are: & for &, < for <, > for >, " for double quotes, and ' for single quotes.
Can I safely paste encoded HTML into a page?
Yes. HTML entities are escaped for safe display. You can also preview decoded content to verify output before use.
