I'm trying to get my Kindle book set up on CreateSpace. I have the inside done. After five hours today I have the entire cover/back/spine done. Now that I'm turning it into a PDF the file is over 63 mb and it won't let me upload unless it is 40 mb and below. How on earth am I supposed to reduce it by that? I'm using their template, it's at 300 dpi. The back, cover and spine were all done in Photoshop. once finished I flattened, saved as JPG at the highest quality. I then chose to embed the files one at a time, bringing it into the template PSD, sizing it correctly, etc. Once done, I flattened that document then went to Save As and chose PDF, went through all of those settings, etc. So what am I missing? Because after over 6 hours of this today I am about ready to throw something through a window. Help please!!!
