WorkinTool – Best dedicated PDF compression

WorkinTool is actually a swiss knife for file conversion and compression and it has a dedicated PDF compression feature.

This software offers three levels of compression: Smaller Size, Normal Compression, and Clearer Output.

Of course, the first one is the most effective and it can shrink a several MB file in a few hundred KB.

However, that setting might affect the quality of the images inside the PDF so we would recommend using the second option, Normal Compression.

The third setting can be used if you need to keep your images to a good quality but it’s a tradeoff for the amount of shrinkage.

Other than that, it’s really easy to use it. Just click on the PDF Compression option, drag-and-drop your file, select the compression setting and hit the Compress button.

The same simple process can be applied to images, videos, Word or Powerpoint files.

WorkinTool works on all versions of Windows, and also on macOS. It can be downloaded and used for free so you can at least try it.

Take a look at its best features:

  • Three compression settings available
  • Simple and easy usage
  • Up to 85% compression ratio for the smallest size compression
  • Image, video, PDF, Word and Powerpoint file compression
  • Free to download and use
