Our discussion on the second edition of Take Control of PDFpen with author Michael E. Cohen starts with a little history of the file format, explains why this book is free, then turns to the newest features of the PDF-editing utility. Michael explains why PDFs can get so large and how PDFpen can cut down the size, discusses DocuSign support, the new call-out feature and more. Find out what’s inside a PDF and why that matters, and why you may already have access to PDFpen.
