Everything around the QR code
Design it, check it scans, print it the right size and keep it up to date. Try each one right here.
Design every detail
Choose from 9 body patterns, 9 corner eye shapes and 11 eye dot styles, use solid or gradient colors, and add a call-to-action frame. This is the same renderer the playground and the qrdx React library use.
Open the playgroundPrint it big enough
The minimum size depends on how far away people scan from and how much data the code holds.
Change the link after printing
Dynamic codes point to a short link you can edit from your dashboard, so the printed code never needs replacing. Free account required.
See every scan
Dynamic codes count scans over time, with countries, devices, browsers and referrers.
Hundreds of codes from one CSV
Map the columns, pick a style and download up to 5,000 codes as PNG or SVG in one ZIP. The file never leaves your browser.
