PDF’s can be great and helpful. Usually you have to submit these pdf’s to some where or need to send it to someone. As a result sometimes it is necessary to compress these files so they will go through email or meet system upload requirements. Smallpdf is an awesome site I found that actually takes your pdf and magically compresses the file to a much more manageable size. I tested a 55mb file that needed to be uploaded to the IB website and their limit is 50mb. We compressed it and it was 2.74mb! File went up fast and easy. Try Smallpdf!
