Did you know?
Compress PDF: Reducing the size of a file is referred to as compression.
Reducing the size of a data file is generally referred to as data compression. While in terms of data transmission, compress PDF is called source coding; meaning encoding performed at the source of the data before it is stored or sent. The connection between machine learning and compression is very close; they are both systems that can predict the probabilities of a sequence in a preceding position and consider the entire history to produce optimal data resizing. For prediction, a more advanced compressor can be used.
