QR Code Generator
About this Tool
Choose from WhatsApp, Telegram, Line, or KakaoTalk and enter a phone number or username to generate a QR code that opens a chat the moment it's scanned. WhatsApp, Telegram, and Line use standard web links that open on any smartphone camera, while KakaoTalk supports Channel (플러스친구) IDs or a full Open Chat URL.
