How do I make a QR code for my WhatsApp?

Use the WhatsApp preset, then replace the example number with your own in international format, like 254712345678. The code scans to open a chat with your business number, so customers can message you without saving or typing it.

Can I make a QR code for M-Pesa payments?

Yes. Use the M-Pesa preset and replace the example till number with your own Paybill or Buy Goods till. When scanned with the M-Pesa app, it opens a payment ready to confirm. Always test the code with your own phone before printing it.

Why choose a higher error-correction level?

Error correction lets a scanner recover part of the code that is dirty, scratched, or partly covered. Level H recovers about 30% and is best for small, printed codes on packaging or receipts. Higher levels make the code slightly denser, which barely matters for a regular size.

Will the QR code work if printed small?

Print at a size your scanner can read comfortably - at least 3-4 cm for a poster or pack label, and keep a quiet (white) border around the code. Use high contrast between the dark and light squares and avoid placing a logo over the middle if you need reliable scanning.

Is the QR generator really free?

Yes. Everything happens in your browser - your content never leaves your device, there is no account, no watermark, and no limits. You can generate and download as many codes as you like.

Small code, real customers

What can a QR code do for your shop?

A QR code is the fastest way to move someone from something physical to something digital. Put a WhatsApp chat code on a parcel and a customer messages you about reordering without hunting for your business. Print your shop link on a poster and people browse your products instead of remembering a web address. Show your WiFi code beside the counter and customers connect themselves - no typing a long password.

For M-Pesa sellers, a payment code on the till or a delivery note lets a buyer open the payment screen in seconds. Whatever code you choose, always scan it yourself once with your phone - and with a friend's phone - before printing it in bulk.
