QR Code Generator

Using QR codes well

A QR code stores text such as a link, phone number, Wi-Fi details or a payment address in a square pattern that a phone camera can read. This generator creates the code in your browser, so the content is not uploaded.

Good practice

• Test the code with more than one phone before printing.
• Keep a quiet margin around the code and good contrast between dark and light parts.
• Print at least 2 cm square for close scanning, larger for posters.
• Use a short link, because shorter data makes a simpler, easier-to-scan code.

What to encode

Website links, WhatsApp chat links, contact cards, plain text, email and UPI payment links are common. For a business, link to a page you control so you can update the destination later.

Safety

Scanning an unknown code can lead to a harmful site. Check the preview of the link before opening it, and be careful with codes stuck over other codes in public places.
