Free QR code generator with your logo

QR codes that never expire

This generator makes static QR codes: the link or details are stored inside the pattern itself. There is no server in the middle that can switch your code off or start charging for it later, so it keeps working as long as the web page or details it holds are still valid.

The trade-off is that a static code can’t be changed after it’s printed. If the address might change, point the code at a page you control, or use a dynamic code that you can re-point and that counts scans.

Adding a logo without breaking the scan

QR codes carry spare data, called error correction, so a phone can still read them when part of the pattern is covered. When you add a logo, the generator switches to the highest level, H, which can rebuild about 30% of the code, and keeps the logo to the middle fifth or so. Simple, high-contrast logos scan best.

Keep the code dark on a light background. Light-on-dark codes and pale colours look stylish but many phone cameras can’t read them, so the generator warns you when the contrast is too low.

PNG or SVG?

• PNG for websites, social posts, slides and Word or Google documents. Choose 2048 px if it will be printed large.
• SVG for print and design tools such as Canva, Illustrator or a print shop. It stays sharp at any size.

How big to print it

A common rule of thumb is that a code should be about a tenth as wide as the distance it will be scanned from: around 2.5 cm (1 inch) for a business card or table, and much bigger for a window or a sign across a room. Always keep the white border around the code, and test the printed version with more than one phone.
