Incredibly simple, incredibly effective

I had many pdfs which I needed to upload, but the site would allow no greater than 2MB files. My original pdfs were much larger - some over 8MB. After spending hours trying many different approaches, and many different apps, I tried this one. At first, I was skeptical because there did not appear to be any settings or options. After trying it on my first document, and seeing the large document reduced to a few hundred KB, I doubted what to expect after opening the reduced pdf. Surprisingly, I could barely tell any difference between the reduced and original in terms of quality. I continued using the app on the rest of my documents, and results were consistently stunning. In one case, it reduced an 8MB pdf to around 500K, and the quality was excellent. This app saved me many long hours and headaches.

The only suggestion I have is to have the ability to keep the original instead of overwriting in-place. Still, it keeps it clean to only have a single file to deal with, or wonder where the output is. It is great as-is.

This is now my go-to app for pdf file size reduction.

Not as useful as I had hoped

I tried it on a dozen random PDFs I had on my desktop. Only one was reduced (a large file from NIST) - I guess the rest were already as compressed as they can be.

Also, the following may be a feature or a liability depending on your point of view: the app overwrites the orignial file automatically. So if you want to try it out and perhap not keep the results, you need to remember to duplicate the original first.

Besides the above, it's a simple app that is very easy to use.

Great But Overwrites Original

I spent so much time trying to find a program that did this as quickly and efficiently as this without paying for a monthly services. Super impressed. It not only compressed file to an e-mailable size but my images still looking amazing... which was the biggest challenge of all.

My only complaint is that the app overwrites the orginal file automatically. I wish there were a way to rename and save compressed version.
