    Is there a way to verify a minimum number of pixels or image resolution with the Dropbox upload tool?

    Asked by jmolvik on January 06, 2016 at 01:29 PM

    This is very important for my printing business. I need customers to upload images for printing posters. I am hoping that the Dropbox upload tool can check to make sure that the image being uploaded meets the minimum resolution requirements that I could input.

    Unfortunately, there is no way to limit the allowed resolutions of uploaded images.  It is possible to limit the type and size of files, but not the resolution.
