As a student, I submit many assignments in PDF format. My professor had issues downloading a large report, so I used Cisdem PDF Compressor to reduce the size by 80%. It was quick, and the formatting remained intact. This app saved me during finals week!

I often send design drafts in PDF format, but some files were too large to email. With Cisdem PDF Compressor for Mac, I was able to reduce a 15MB file to under 2MB without noticeable quality loss. The interface is simple, and it's now part of my daily workflow.

I'm digitizing old contracts and receipts. Cisdem's compressor helped me shrink hundreds of scanned PDFs and save a lot of disk space. Sometimes the OCR-based PDFs don’t compress as much, but overall, it does a great job. Would be nice to have an auto-rename feature when batch compressing.

I've purchased it for some time, there is some bugs with the program, and I have emailed the support team. I recently upgraded to the latest version, the new version works amazing. Well, Cisdem is a company who really solves the problem for users, thanks and keep on good work!

Purchased this program cause I need to send some files via email's attachment. It is working excellent with the files included images, but for files included texts only, it is not working. Just in case of someone who do not know it either.

It seems not a hard work to compress the PDF size with multiple programs, but the effect with Cisdem PDF Compressor is the best I used before. It compressed a 4.5MB file to 830KB, also you could select custom option to select your desired size. Really convenient and intelligent!

Good app! It did the trick, quickly and easily. I couldn’t email a 180MB pdf document because it was too big. This app compressed the 38MB document to 6.5MB, which wasn't even the highest compression level. The email went quick. I was scared it might have corrupted my document, but they opened just fine on the receiving end. Highly recommended.

I have a lot of PDFs for insurance-related work and was very frustrated by the amount of space (and size) that the PDFs took up on my computer…not to mention, how difficult it was to send them to the proper people for their records. This program is very easy to use and is definitely worth the money.
