[v6.1.x] DiffPDF – Compare PDF files quickly and easily

A pre-press producer often has to proofread a document. The usual way is to open the source on the left, open the manuscript in production on the right, then carefully look for differences. The overall process is really tedious, lengthy, eye-straining, energy-consuming, maddening, and most often there are omissions. If you often have to compare PDF documents at work, DiffPDF can help you finish the document comparison work easily and efficiently.
