Why Does PDF Open in Chrome?
Understanding the PDF File Format
Before we dive into the reasons why PDFs open in Chrome, let’s first understand the PDF file format. PDF (Portable Document Format) is a file format that allows multiple documents to be combined into a single file, preserving the layout and formatting of each document. This is achieved through the use of a proprietary format that is not editable by the user.
