What is the QR Code Generator?
A QR code lets anyone open a link, join Wi-Fi or start a WhatsApp chat by pointing their phone camera at it. The QR code generator creates static codes that never expire, with your choice of colours, size and error-correction level.
Put them on packaging, visiting cards, menus and shop counters. For product and carton barcodes use the Barcode Generator; for shipping labels use the Shipping Label Generator.
How to use the QR Code Generator
- Choose the type: link, text, WhatsApp, Wi-Fi, phone, email or SMS.
- Fill in the details.
- Choose colours, size and error correction.
- Download PNG or SVG and test it with your phone.
Example
A WhatsApp QR for +92 300 1234567 with the message "Hi, I want to order" opens a chat with that text ready to send.
Tips for QR codes that scan
- Keep dark code on a light background.
- Print at least 2 × 2 cm, larger for scanning from a distance.
- Leave a white border (quiet zone) around the code.
- Use higher error correction if you add a logo.
- Always test before printing in bulk.
