You can upload your own design using the ‘Upload Your Design’ templates visible in each category and then use the ‘add image’ button.
The supported file formats include JPEG, TIFF, PNG and PDF (one file per page). The size of the files must not exceed 30mb. The actual size of the cards is provided when you pick a size and format (below the ‘Upload Your Design’ thumbnail).
For images where you want the background to be transparent, and not printed, please use the PNG file format with no background included.
NOTE: It is preferable to use files which have the colour profile CMYK instead of RGB, as this usually ensures more accurate colour reproduction.
