Compress PDF files easily with Densify in Linux

Densification It is a graphical user interface that simplifies the process of compressing PDF files on Linux using Ghostscript.

The tool uses Gtk and is written in Python. It uses a simple interface that allows users to select the PDF file to be compressed, PDF optimization level and output file name (compressed.pdf by default, so the original file will not be overwritten) .

Click? Can explain the PDF optimization level. The button is under “Type” as shown below:

  • Screen: Choose a low-resolution output / 72 dpi image similar to the Acrobat Distiller “Screen Optimizer” setting
  • E-book: Choose a medium-resolution output / 150 dpi image similar to the Acrobat Distiller “e-book” setting
  • Printer: Choose output similar to “Acrobat Distiller” “Print Optimization Settings / 300 dpi image
  • Prepress: Choose an output / 300 dpi image similar to Acrobat Distiller’s “Prepress optimization” setting
  • Default: Choose output intended for multiple uses, possibly at the expense of a larger output file

You will need to try these settings and see which one is best for your use case. For example, the PDF optimization level of the screen and e-book will further compress the PDF, but after zooming in a little, check the quality to see if you are satisfied.
