The most common file type for business and communication, this compact portable document format is widely used to collect as well as present information, as well as being equipped with many lesser-known features that can keep your content secure while making it easy to share. From archive features that will keep your documents available for years to come to features related to accessibility, organizing, annotating, editing, and whatever else you use PDFs for, Acrobat has the answer if you know where to look. Designed for professionals who likely already use Adobe Acrobat Pro, this guide introduces many ideas, features, and online services, sorted and organized for you to easily find the topics relevant to your work and requirements. You can jump to any chapter without sifting through prior pages to explore the tools and functions explained through step-by-step instructions and examples.
