So I'm trying to use Automator in order to turn a bunch of pictures I have into a single PDF document. The images are separated into about 300 different folders, with about 20 images per folder. The current settings I've been using for Automator are: 1) Ask for Finder Items (Allow Multiple Selections is checked) 2) Get Folder Contents 3) New PDF from Images (Size Each Page to Fit) And it works. It gets all the images into a single PDF, which is great. However, it changes the sizes of some of the pictures randomly. Most of them are the right size, ~600x1000, when they are PDF-ified. However some of them become much smaller (about half the size), even though all the pictures have about the same dimensions in JPG format. However, when I convert each folder by hand to a PDF via Print -> Save as PDF, all the images are converted to PDFs as the same size, none are smaller than the others. So I'm pretty sure it's a problem with Automator rather than the pictures themselves. Can anybody tell me why some of the pictures are made smaller during the conversion and how I can fix it? I've tried using the other sizing options under "New PDF from Images" but that just adds an enormous bezel to the smaller pictures while keeping the bigger ones exactly the same.
