PDFsam Portable

PDFsam Basic Portable, a free, open source, multi-platform software designed to split, merge, extract pages, mix and rotate PDF files packed as a portable app so you can do your PDF 'split and merge' on the go. It has all the same features as PDFsam Basic, plus, it leaves no personal information behind on the machine you run it on, so you can take it with you wherever you go.

The ‘sam’ part of PDFsam's name means ‘split and merge’, and this is a large part of what the tool is designed to do.

As well as making it possible to merge multiple PDFs into a single file, PDFsam Basic offers you no fewer than three ways to split PDFs. You can split using page numbers as a marker, using bookmarks contained within a PDF file, or into chunks of a particular size.

You can merge several whole entire PDFs into a single file, or extract and combine smaller sections.
