What’s New

Version 2.0

- Added new Monochrome color model compression option. Selecting Monochrome color model compression option converts raster PDF contents into black and white which helps reduces PDF file size to greater extent. It is very helpful when compressing scanned books mainly containing text. Optimizing PDF using Monochrome color model can create 24 times smaller PDF compared to RGB color model compression.
- Addressed user reported file specific crash and other bug fixes.
- Minor UI changes.
- Other improvements.

Perfectly simple

I use Notability to document construction jobs, taking pics and adding comments,however after multiple pages of photos, the file becomes too large to export from the app into an email (4 page note was 37MB😑🔫). I tried exporting the file to various apps (Drive, PDF converter, acrobat, docs2go) but there was no work-around to the too-big-to-attach file size. Three bucks later I download this app and boom, file was compressed and emailed. The app really is perfectly simple. I sent it to the app right from Notability. Once in the app I played around with the various compression sizes, emailing myself different settings until I had the perfect size for photo quality and email attachment. This app is a lifesaver. Well done developer, you truly have created a solution.

This app is nothing short of excellent. Inexpensive, works as well if not better than desktop alternatives. If I had one complaint I wish the compressed documents were stored on iCloud so I could access the documents I’ve compressed on any of my other devices. I’d love to see an app this simple and effective on macOS too. Really great job! Also hugely appreciate all work is done on-device when compressing sensitive content.

Developer Response ,

Thank you very much for your feedback.

Regarding your complain, you can use inbuilt Add or Send to iCloud Drive share activity option to save optimised PDF on iCloud Drive. You can also use Save to Files activity option on iOS 11 to save compressed PDF file on cloud storage drives.

Regarding your wish, PDFOptim is also available on the Mac App Store. It is as intuitive and more powerful on the macOS.

Excellent app

This app saved the day for me. I do volunteer marketing for charity, and I had done a newsletter that was quite vital to the success of an upcoming charity sale. I took a chance and downloaded this app this morning and, in no time, it reduced a 23MB doc to an easily-transmissible 6MB, maintaining perfectly acceptable clarity. My newsletter will now be able to reach thousands of people, and our sale stands a better chance of success. The all operates very easily. You will love it.
