The application is very simple and user-friendly. Just select the level of compression (recommended, high quality, large size, or low quality), and the file size you want to achieve. This app will then use its advanced compression algorithm to optimize the PDF file size for the selected level. After the process is completed, you will get an informative report on the status of your PDF file.

The best part of this app is that it's free, so there is no need to pay to use it. You can choose from three different compression levels (recommended, high quality, large size, or low quality). To set the compression level, you can use the seek bar. The larger the compression level, the smaller the file size.
