Create a QR Code: tools and apps

What should you compare?

Scan the code you made with several phone cameras, on screen and printed on paper. If you added a logo, changed colors or made the code small, check readability again; leave a margin around the code and use a dark code on a light background.

Dynamic codes may let you change the destination later and see scan counts, but the code is tied to the service account. Check the official pricing and terms page for whether the code keeps working after a free trial or subscription ends, and what personal data scan statistics collect.

Do free QR codes expire? A static code carries its own information, so it works as long as the destination stays online. Time limits usually apply to the redirect service behind dynamic codes; confirm which type you created before sending it to print.

Which file format should I use for print? For large prints, vector formats such as SVG or EPS stay sharp; with PNG, choose a high enough resolution. Print a test at the real size and scan it before the final run.
