Recently I came across Smallpdf – a web service dedicated to all things PDF. They have a range of services which simplify creating PDFs, extracting them, manipulating them and compressing them. The service is free and very fast – and a worthy companion for anyone who struggles with compressing PDF files to a small size (without degrading image quality for print), merging PDF documents or extracting PDF pages. It has a very simple menu, doing what it says on the tin. Highly recommended for all bookleteers out there.
