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.
Reducing the file size of a PDF file using the online converter involves the following steps:
- 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.
- Step 3: Once the file has been selected, Foxit will automatically perform the conversion.
- Step 4: After the conversion is complete, a message will pop up prompting you to download the file.

How to Reduce PDF Size with Foxit PDF Compressor Alternative
As earlier discussed, PDFelement is an alternative to Foxit PDF Compressor that provides the same functionality at a friendlier price. To compress a PDF file, the following steps are taken:
Step 1: Open the PDF File
On the application, click on "Open File". This will enable you to select and upload your PDF document.

Step 2: Compress PDF with Foxit Alternative
Then, click on the "Optimize". Clicking on Optimize will lead you to a new page where you are able to set the properties of the file to be optimized. The page contains a slider that moves left and right to adjust the level of optimization to be carried out on the file. Moving the slider to the right side will result in very low optimization. Moving it to the right side on the other hand leads to the maximum level of optimization possible. As the slider moves, the file size and level of optimization being carried out will be displayed below the slider.

When you are satisfied with the new file size, click on the "Optimize" button located at the bottom of the page to complete the process.
