Frequently Asked Questions
🔤 What is HTML encoding?
HTML encoding converts special characters (like < > & ") into their corresponding HTML entities (< > & ") so they display correctly in web browsers.
🔒 Is my data private?
Yes! 100% client-side. All encoding/decoding happens in your browser. Nothing is sent to any server.
🎯 When should I use this?
Use when displaying user-generated content, embedding code in HTML, preventing XSS attacks, or working with HTML emails.
🔄 What's the difference between encode/decode?
Encode converts characters to entities (safe for HTML). Decode converts entities back to their original characters.
