QR Code Generator

What is a QR code generator?

The Dopinggo QR generator creates scannable codes for product pages, payment links, campaigns, and store URLs—free for merchants.

What can I use QR codes for in e-commerce?

Common uses include packaging inserts, invoice links, in-store displays, catalog access, and campaign landing pages.

Which download formats are available?

Export as PNG, JPEG, or SVG. PNG/SVG suit print; JPEG works well for digital assets.

Can I change QR resolution?

Yes. Choose between 200 px and 1200 px using the size slider—higher values are better for large print.

Can I add my logo?

Yes. Enable the logo option to place your brand mark in the center while keeping enough contrast for scanning.

Can I customize colors?

Yes. Set foreground and background hex colors. Strong contrast improves scan reliability.

Is the QR generator free?

Yes. It is free with no usage limits on Dopinggo.

Do QR codes expire?

Static QR codes do not expire unless the destination URL changes—then generate a new code.

Should I use HTTPS URLs?

HTTPS is strongly recommended for security and compatibility across devices.

How do I test a QR code?

Scan it with your phone camera or a QR reader app and confirm it opens the correct page before printing.
