Learn how to reduce the file size of PDFs on your Linux device using the command line and online resources.

Multi-page PDFs can quickly become too big to email or upload. Luckily, there are a few ways you can compress files to make it easier to handle larger PDFs. Here are the best ways to compress a PDF with Linux.

Linux PDF compression with command line utilities.

If you run Debian or Ubuntu, you can compress PDFs with the Ghostscript command line tool. Ghostscript is software that interprets and compresses certain file types, so your Linux device can read and edit PDFs.

When at work or school, or if you are writing a book, you may want to scan a document and then save them as PDFs. Sometimes these PDFs can be too big or take up too much space on your device, which can make them impractical to send via email or upload to the cloud. Ghostscript can help you compress your PDFs so they are easier to share and store.

How to open a PDF file in Linux command line.

If you are wanting to open or view a PDF file while working from the Linux command line, you will need to launch or install Evince on your Linux computer system. Evince is the application that Ubuntu, a Linux operating system, defaults to as its PDF reader.

If you do not have Evince installed on your Linux computer system, you will need to enter the appropriate command line for your operating system version.

Once Evince is installed on your computer system, you will need to follow these steps to view or open a PDF file from the Linux command line:

  1. Go to the directory and enter the command line: $ cd downloads. By entering this command, Evince will open for operation.
  2. Type the command line: $ evince file.pdf. You can also enter: $ evince /Downloads/file.pdf.
  3. Your PDF should open in your PDF reader.
