PDFOptim

This app is the best, on apple store. Very understandable design. Smart price for lifetime use. Team who did create the app - you are best. Thank you

This does an amazing job in my early usage at reducing PDF size while preserving decent quality. Thanks! It’s a bit disappointing that it does not support iOS shortcuts, and that you need to buy another copy if you want to use it on macOS. That makes it a bit pricey for a single-purpose utility app.

I compose “how-to’s,” “tips ‘n tricks“ and recipes that I like to send & share with friends & family. These require photos & screenshots because ("A picture is worth a thousand words".) Invariably these documents run into trouble when I try to paste them into an email. Either the pictures are moved around, or the text gets scrambled about, or most often the file refuses to email because ‘it’s too big.” PDFOptim let’s me save my documents as PDF files that are 90%+ smaller than the raw documents. I’ve been able to email the small PDF documents as mail attachments without fail! Price was reasonable & it does the job I need. Takes a bit of time to get the hang of it, but easy after a few goes.

I use an iphoneXR. I tried opening the app after an update but it can't open again. What do i do?

I just bought it and tried to compress the 1.9mb file it compressed to 1.6mb at all settings. It is of no use. I have to get this one refund from the developer.

Why is it my PDF Optim app no longer works?? I paid for this app and have been using it for several months now, and suddenly, when I really needed it today, it won’t open on my iPad!! Soooo frustrating!

Needed to compress a large PDF file. Did NOT want to sign up for an Acrobat monthly overpriced subscription. Found this app after doing some searching. It works ! Just tinker around with the compression settings to find the optimum for each PDF you need to compress. Do a few tests, to find which one best suits your requirement. This app was well worth the fee.

Wish I could get my money back. Reduced my file about 15% but graphics were unreadable or highly degraded. I played around with the settings and couldn’t get anywhere near the other reviewers results. Hmm... Conclusion: a waste of 3 dollars

Making PDF files smaller is probably the one thing that about everybody needs at some point. There are hundreds of apps that will mark up, save, reorder pages and stuff with PDF files (Good Reader is my personal favorite) but none of them will help you get a a 30mb PDF down to email size. This does it without an annoying subscription. Simple, affordable, worth every penny. I squished down a 25mb PDF to 3mb and couldn’t even tell the loss in quality. A life saver.

This app costs $2.99 once and will compress pdf files on the iPhone forever. “Free” apps will compress your file, but force you into a monthly subscription to retrieve the file. This app is easy to use and did exactly what I needed.
