Open the Design tab
Open a saved QR code and select Design. The preview shows the saved short URL using the current appearance. Changes remain in the editor until you select Save design.
Choose the appearance
Use the design controls to change the sticker treatment, colors, module and corner shapes, and logo. The available combinations update the preview without changing the destination or routing settings.
Keep the code scannable
Use strong contrast between the QR pattern and its background. Keep the clear margin around the code, and avoid a logo that covers too much of the pattern. Test decorative designs with a real phone.
Save and download
Select Save design to update the saved code. Download the code again when you need a file containing the new appearance. Previously downloaded files do not update automatically.
