We can work with a very wide variety of image file formats although our preference is for level 10 JPEG files or PNGs depending on the product. 

We use JPEG’s because the compression is very efficient and designed specifically for saving photographic images. Although some image data will be lost during the compression process, at high quality levels there is no meaningful difference between a level 10 JPEG and a Tiff printed to paper. 

PNG files have built-in transparency but can also display higher color depths, making them ideal for t-shirt graphics. 

In our BigCommerce and Shopify Apps - you can upload TIFF, JPEG and PNG files. 

Other file formats such as PSD and PDF are unfortunately not supported at this time. If your design has a transparent background, you can retain this with TIFF or PNG. 

TIFF is not currently supported for API or manual order form orders.
