A compressed PDF document has the advantage of being smaller in size than its original and therefore takes up less storage space, making it faster to upload if you need to transmit it. You will be able to use the built-in Adobe® Acrobat DC Pro compressor, but you will have to pay the price of a license or settle for its trial, time-limited version, which is free. You can also compact your document using the HiPDF online compressor and if you are on Mac, Preview will provide you with this service without difficulty.
