PDF compression procedure tackles the `size problem' by discarding unused data, replacing repetitive data by certain logic, using low dimension vector graphics, restricting embedded fonts, preferring bitonal/grayscale image modes, etc. Compression can be lossy (lower size) or lossless (better quality) based on the algorithm used by the compression tool. The outcome is in the form of an optimized PDF file that overrides its source by exemplifying efficiency and effectiveness.
PDF compression free download software, alias free PDF Compressors, are utilitarian in nature. Their fundamental functionality is to contract the input PDF file using built-in algorithms and reproduce an equivalent, yet compressed file which can navigate at a better speed via a network. A PDF compressor may use a single algorithm or offer the user a variety of choices based on the software complexity. Similarly, many updated compressors allow a user the liberty to manage the level of compression as per their requisite.
