What Is a WhatsApp Chat Widget?

A WhatsApp Chat Widget is a floating button or popup that appears on your website, allowing visitors to start a WhatsApp conversation with you in one click. When a visitor clicks the widget, WhatsApp opens with a pre-filled message ready to send — no need to save your phone number first. The widget typically appears as a small circular button in the corner of your website that expands into a chat popup with a welcome message. OPN Chat Widget Generator lets you create this widget for free, customize its appearance and behavior, and get a ready-to-use HTML code snippet that you can embed on any website or platform.
