How to make a QR code
Making a QR code takes about a minute. The part most guides skip is what happens after you print it, so this one covers that too.
Pick what the code should do
Decide where the scan should go. A website link, a restaurant menu, your contact details, Wi-Fi access, and a dozen other types each have a dedicated form. If you are not sure, a URL code is the most flexible because you can change the destination later. Browse the full set on the generator.
Create and customize it
Add your colors and logo so the code matches your brand. Keep a clear contrast between the code and its background, because low contrast is the most common reason a code fails to scan.
Download the right format
Use PNG for screens and slides. Use SVG or EPS for anything printed, because vector formats stay sharp at any size, from a business card to a banner.
Test before you print
Scan the code with two or three phones before you send it to print. Check it in the lighting where people will actually scan it.
Keep it editable after you print
If you make a dynamic code, you can change where it points at any time without reprinting. That means a typo, a moved page, or a new campaign never means a new print run. See static vs dynamic QR codes for the difference.
