Quick answer

To create a WhatsApp QR code for free, enter your phone number with country code (for example, +15551234567) and an optional pre-filled message in the KaviForge WhatsApp QR Code Generator. It builds an official `https://wa.me/` link and renders a downloadable PNG QR code locally in your browser.

Make it effortless for customers, leads, and event attendees to message you on WhatsApp without having to save your phone number in their contacts first.

This generator encodes an official WhatsApp `wa.me` deep link with URL-encoded pre-filled text directly into a static QR code—so it never expires, has zero scan limits, and never routes through third-party tracking servers.

How to Create a WhatsApp QR Code

1Enter your WhatsApp phone number including the international country code (e.g., `+15551234567` or `+447911123456`).
2Optionally type a pre-filled message (e.g., "Hi! I scanned your QR code and have a question.").
3Choose your preferred image size (up to 1024px) and brand colors.
4Click "Download PNG" or copy the Base64 data URI to embed on your website.

How WhatsApp Click-to-Chat QR Codes Work

WhatsApp supports official universal links in the format `https://wa.me/<number>?text=<encoded_message>`. When a smartphone camera scans a QR code containing this URL, it launches WhatsApp and opens a chat window with that phone number and pre-populated text.

Always include your country code (without leading zeros or spaces) so the link works for international and local scanners alike.

WhatsApp QR Code Generator FAQs

How should I format my phone number for a WhatsApp QR code?

Include your full country code followed by your phone number (for example, `+15551234567` for US or `+94771234567` for Sri Lanka). The tool automatically strips spaces, dashes, and the leading plus sign to match WhatsApp’s `wa.me` specification.

Does this WhatsApp QR code expire?

No. Because it encodes the direct `https://wa.me/` URL with no middleman redirect, the QR code works forever with unlimited scans.
