Stupendous!
Best $2 I’ve ever spent. Bought this app to compress PDFs I had generated from my scanner. The app allows you to drag and drop your file(s) and gives you a number of different DPI options with estimated file size. I chose medium quality (150 dpi) and my document shrunk to 10% of its original size! Nice. The other functions like concatenate, split, etc. work just as well and as easily.
