How to use this tool

International number format
Enter 8–15 digits, optionally preceded by a plus sign. Do not include spaces, brackets, or dashes. The plus sign is removed when building the wa.me link.
Bounded QR payload
Messages are limited to 1,000 Unicode characters, and the complete WhatsApp URL must fit within 2,048 UTF-8 bytes. A fixed 512-pixel QR canvas keeps rendering bounded.
Local generation
The link and QR image are generated in this browser using the installed QR library. Inputs are not uploaded or stored. Scanning the QR code opens WhatsApp when supported by the device.
