Free Download DropCompress 1.2.13 (x64) | 65.6 Mb
DropCompress makes it possible to reduce and optimize several PDF documents at once directly by drag & drop or via a monitored folder. DropCompress is an executable MS Windows application that can be started automatically. Optimizes and compresses existing PDF files many times over, depending on the initial situation and settings.

One of the main features of the PDFCompressor component, in addition to the reduction of the resolution, is that PDFs can be created with the latest and best compression methods - JPEG-2000 and JBIG-2 which are not supported by most PDF applications.
It may make sense to unify all PDF files in the company in terms of compression and resolution in order to obtain a uniform standard for all received, processed and archived PDF documents, regardless of where the PDF files came from.
