Yes.
What I do is put the PDF into DEVONthink from wherever it originates. Normally, “today’s” view shows all my work for the day. At some point I will batch convert by selecting them all, dragging them into PDF Squeezer window, and let it rip. Then “save” back into place in DEVONthink. I’ve gone back and compressing some older PDFs before I had this tool and I’ve done a few hundred at a time.
For the typical web article with a lot of text and one over-sized photo at the top … with “strong” i’ll get 90% or greater compression, mostly on the image which I don’t care if it comes out fuzzy. “Medium” still squeezes signficantly but leaves the images not fuzzy. I’m not very picky.
They also provide what they call “automation” tools, but I’ve not gone there due to an odd error message that occurs when I press the “grant access” button and so far the developer hasn’t gotten back to me in reply to my query. That apparent lack of support is my only reservation about this tool. There are surely other tools like this available.
Their downloaded version might have a test period. Dunno. I got my copy from the Apple app store.
