We accept a wide range of file formats including JPEG, TIFF, and PNG.
As for file size, 300 dpi at size/printing resolution works best. In general, the larger the file size the better the quality. However, file size does not necessarily determine photo quality. We set minimum resolution requirements on each product, so if your file uploads successfully it will look great for that size.
You can upload and test your image here. Our system will display the pixel dimensions of your image so you know which product sizes will work best.
(Note: if your image is larger than 200MB or 75 megapixels the system will still accept it but the image preview may not display on your screen).
