How can I reduce the size of a PDF?

Reducing the size of a PDF file is referred to as data compression. In terms of data transmission, it's source coding: encoding performed at the source of the data before being stored or sent. Security connection between machine learning and compression is close: both systems predict the probabilities of a sequence in preceding position and consider the entire history to produce optimal data resizing. For prediction, use more advanced compressors PDF tools.
