You can either download the QR Code as is, or
apply a design, in the QR Code's options pane.
After creation, open a QR Code's options pane and select Download or Design QR. Download your QR Codes as PNG, SVG or PDF, and as EPS or DXF without designs; this will mainly depend on whether you want to print your Code, use it in digital media or have a special use case.
Choose one of the the offered formats to start the download. Alternatively, you can directly print the QR Code; please make sure to fit the QR Code to the page in the printing options.
