PDF Compressor is a utility tool that helps compress PDF files to any size, either in a batch or individually. This helps decrease the total space files occupy on your computer. A PDF file has its unique set of advantages, but the major downfall to them is the size they come in. The large size not just eats into your hard drive but transferring the file to an external drive takes time too. The tool can be used by amateurs and experienced users. The primary interface consists of a non-adjustable, medium-sized window. The files could be added with the help of the explorer interface or by the drag-drop functionality.
