PDF is a format that has gained massive popularity over the years due to its portability. This file format is also highly appreciated since it can handle both text and images seamlessly. At the same time, storage space is increasingly becoming more expensive. It is vital that individuals and organizations try as much as possible to maximize the available space. One way of doing this is by compressing PDF files using third party applications. One of the best software available in the market is Foxit PDF compressor which we will be using as our reference point in this article.

How to Reduce PDF Size with Foxit Editor and Online Service

Reducing a PDF file size using Foxit is possible in two ways: using an online converter and using a PDF optimizing tool found in Foxit Phantom PDF software.

  • Step 1: Open the Foxit online website on your web browser.
  • Step 2: On the homepage of the website, you will be provided with two options of selecting the PDF file to be compressed. You can choose to drag the file onto the specified location or select it on the storage location where it is stored.
