DISAPPOINTING UPDATE:Since v3.0, this once-perfect app has been getting worse and worse. Options have been removed, then some added back in but in a hidden and convoluted way, compression has gotten worse (one “compressed” PDF came out *bigger* than the original). I’ve reverted to v2.7 from my Time Machine. I’ll keep this app on my drive just to see if it improves with updates, but as of 2020-11, it’s very much headed in the wrong direction for an app that’s gone from free to $23.PREVIOUS:Just got done testing several PDF squeezers — this one’s the clear winner. When I’m looking for a new app, I get obsessed with finding the best one for me. I download any I can find that look like they might fit the bill, then I put them through the paces. After testing half a dozen PDF squeezers against each other (color-scaned PDFs, text-scanned PDFs, downloaded user manuals, etc.), PDFify performed best on *almost every test*. It consistently produced the best quality with the smallest file size. I settled on 300dpi/low quality as the best setting (“low quality” is a misnomer — the PDFs looked great), but there are 7 other options). The fact that it also had the clearest, friendliest UI is a nice bonus, as is the OCR functionality, which I’ve only played with a little, but it seems to do a great job of that too. And it can read text aloud, and scan — which I’ll probably start using so I can immediately squeeze the PDFs I create. There are a *lot* of paid apps (some quite expensive) with similar functionality that don’t stand up to this free one. Really glad I found it.
