This tool lets you make your own cards, by generating a print-ready PDF from the images you upload. Each image will be scaled so that the final printed cards have the correct size.
You can optionally add a back image that will be used on all cards. Once the PDF is generated, you can preview it and download it for printing.
When printing, be sure to select "Actual size" or 100% (not "Fit" or "Scale") to ensure proper dimensions.
