PDFOptim App Reviews

Very easy to use and it works!

It’s amazing.

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 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.

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

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.

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

Not sure how this wasn't reviewed previously. Total gem. Easy to use software and scaling ability for compression. Also shows side-by-side window to compare compressed version with original.

I was able to reduce the file size of my PDFs at one quarter the original size. Thank you for this awesome app!

Awesome! Very easy and fast to use. Took my e-Book (Vinyl Rocks) from 690 MB to 114 MB with no visible difference. Thanks!

excellent, easy to use, converted my 44mb pdf down for easy email right on my phone! very satisfied app is extremely efficient and quick too

Simple to use and very effective!

This is the only thing that works. I’ve needed this for years. It’s instantaneous.

This is brilliant application to use and worth to spend the money . Way excellent -

What more could you ask for? The one time I thought there was a problem, it was my own screwup. This app is great. The developer promptly responds when questions are asked. Go for it, it’s worth the money.

It compressed my files seamlessly and easily. It has nemerous options as to what quality and size you want your file to be compressed to and the side by side comparison between the original and shrinked one is absolutely awesome. Very reliable..

Simple and it works. It shrinks PDFs. Thank you.

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.

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!

I have 200 MB notebooks from good notes, this thing could only get it down to 50 MB, which is great but not good enough. The algorithm clearly only messes with the photos in the PDF, but as GoodNotes seems to save the handwriting as a really high resolution background for the PDF, the algorithm doesn’t optimize it at all. At 1ppi, which is an ultra low setting the images become indecipherable, but the handwriting is crystal clear. I’m going to get a refund.
