By Adobe – December 15, 2014

Learn how to combine and merge PDF from multiple sources—including text files, spreadsheets, emails, web pages, scanned paper, and images—into a single PDF file that brings all your information together in one place. Use the new Thumbnail view to preview, drag and drop, and arrange documents or individual pages before combining them into a PDF file—just like sorting presentation slides.
