I don't generally write reviews about apps, but this one deserves it. I bought this app because I'm migrating from NeatWorks, over to Evernote for my filing. I noticed pretty quickly that the file sizes on most of my scanned documents were a bit too large for me and chewing through my monthly upload limit with Evernote.
I decided to check around and see if there was an easier way to compress the PDF's I already have, instead of dealing with them one by one. I checked out a few apps and settled on PDFOtim. I loaded up a batch of 1,150 receipts into the app. I was a bit shocked when it processed all 1,150 of them in less than 2 minutes.
The default settings weren't to my liking, as I wanted a higher DPI and by simply selecting all of the files currently opened and changing the settings on the right, the app went back through and changed all my files, applying the new settings. This is a big plus for me and I went from 524MB total size, down to 183MB. That's roughly a 65% savings in space.
Even saving them to disk was super fast. I was able to save all 1,150 receipts in under a minute. Granted, I am using an SSD as my primary drive. But the simple fact that the app was able to handle that many files at once, processing, edit, saving, ect. is impressive.
