Preview, Popup & Zoom
Inspect the live QR design at different zoom levels and open a larger popup directly from the preview image.
Live preview
The QR is generated locally in your browser. CTA frames add height while keeping the CTA body aligned to the QR width. QR data is not sent to an external rendering service by this Designer.
Enlarged preview
Select the QR preview canvas itself to open the popup. The preview is keyboard accessible: Enter or Space opens it and closing the popup returns focus to the preview.
Zoom
Use Fit, 50%, 75%, 100%, 125%, 150%, or 200% preview zoom.
Mobile preview
On mobile the preview is sticky and includes a Show/Hide Preview control so you can keep the live QR visible without losing too much editing space.
