Some experimentation may be necessary to find a suitable balance between file size and image quality. The options between Minimum and Maximum will produce images with properties between those two extremes. Maximum will create an image with the highest level of precision, but the largest file size. Minimum will produce an image with the lowest level of precision, but the smallest possible file size.
There are five options: Minimum, Low, Medium, High, and Maximum. JPEG Quality: Determines the compression level used for JPEGs.Photographs (JPEG): Uses compression designed specifically to work well for PDFs that contain photographs.Select from the available options to determine how much (if at all) images should be compressed.
