Overview of this book

Adobe Acrobat can help you solve a wide variety of problems that crop up when you work with PDF documents on a daily basis. 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. The information in some chapters may build on existing knowledge, but you are not expected to have an advanced level of prior experience. By the end of this book, you’ll have gained a solid understanding of the many capabilities of PDFs and how Acrobat makes it possible to work in a way that you will never miss good old ink and paper.

Removing hidden content and sanitizing a PDF document

Hidden data and metadata give away a lot of information about a document. The author, date of creation, the application that created the .pdf, digital signatures, form fields, scripts, and more. You can remove all this information in one step or choose selectively what should remain in the document.

We will use the Sanitize Document feature found on the Redact toolbar. It is also a default option appearing in the Apply Redactions alert box that we turned off before. Here are the steps:

  1. Click Sanitize Document on the top toolbar and then click the Selectively remove option. The Hidden Information pane appears on the left of the screen. The dropdown options allow you to show all items that Acrobat is looking to remove or just those that are found in the document. Here is a screenshot:
