Simple but does exactly what it says- merging, splitting PDFs, no errors.. Filesize stays then the same. Compression was untested by me.
I needed the qpdf tool to compress a PDF file. The following compression results were achieved: Original PDF, 3 pages: 52.4 MB Four adjustable compression settings produced file sizes of 219 KB, 619 KB, 4.1 MB, and 7.3 MB I am very satisfied with the result.
