How to use it
A readable QR code, even when customised
Enter a link or text, choose size and style, then check the preview before downloading the PNG. For printing, use at least 512 px, leave a clear margin around the code and maintain strong contrast between QR and background.
Centred logo
Upload a PNG or another image. High correction and a background behind the logo help phones read the code.
Final check
Before publishing, test the QR code on two phones and from the actual scanning distance.
