Frequently asked questions
Do these QR codes expire?
Never. The data is encoded directly into the image — there is no redirect service in between, so your QR code works forever and doesn’t depend on any company staying in business.
Can I use the QR code commercially?
Yes — codes you generate are yours, free for menus, posters, product packaging, business cards and anything else. No watermark, no attribution needed.
What size should I download for print?
Use 1024 px for posters and flyers. As a rule of thumb, print the code at least 2×2 cm for every 10 cm of expected scanning distance.
Can I make a UPI payment QR?
Yes — paste a UPI string like upi://pay?pa=yourid@bank&pn=YourName&am=100 and any UPI app will open payment on scan.
Will colored QR codes still scan?
Yes if contrast stays high — dark foreground on light background. Avoid light-on-dark or low-contrast combinations.
