What’s the format limit & suggested picture size/resolution?

POPCUSTOMS supports RGB color mode and JPG, PNG, and BMP image formats. The recommended size and pixel requirements are shown on the create page. Files should not be larger than 60 MB.

You can upload images smaller than the recommended size, but the print result may look blurry. Some products, such as tapestry items, require larger images. The design tool will also show a print quality notice when you upload an image.
