Great app, except that it compresses PDFs and loses image quality. I have PDF documents of artwork made from scanned paper. 33mb file, after reversing page number, the file is now 25mb. Would like to have reverse page order without compression. The same method provided by this app, can be done by opening a PDF file in Preview and selecting File>Print>Paper Handling>Page Order:Reverse and instead of hitting the "Print" button, select "Save as PDF". Don't have to pay $3, I paid for the app hoping it would not compress the file size and quality, otherwise I would've just stuck to the Preview method - it's free with your Mac OS.

Incredibly easy to use. It was a little slow on my 2016 MBP, but my file was a 700MB pdf. It took about 2 minutes to process, but saved me probaby 45 minutes to an hour of rearranging...worth $2 for sure!I also like that it just gives you a checkbox to save to the destination folder without having to browse to a new location each time (and it names the file by appending "reversed" to the file name). Well done.
