Getting Started

PDF Infinity is available for download from the Microsoft Store. Visit one of the following two links to get started:

PDF Infinity supports both Windows 11 and Windows 10.

Start the app

Once the application is installed, launch the app following these steps:

Click the Windows Start button
Type “PDF Infinity”
Locate the matching program entry with this app icon
Click the entry to launch the app

For ease of access in the future, you may choose to pin the program icon to the Windows taskbar. With the app running:

Right-click the app icon from the taskbar
Select “Pin to taskbar”

The Launch window

Once the app is launched, the Launch window is the first interface that greets you. It is the launch pad that provides you with quick access to any of the core functionality groups.

The launch window is divided into three main areas:

The Open File zone: is where you can browse for and open a PDF file. You can either click the “+” browse button to locate the file on your computer, or you can simply drag and drop the file onto the zone.
The Quick Access zone: provides entry to the main functional groups of the app
- View PDF and docs
- Annotate PDF
- Edit PDF pages
- Manage PDF files
- Convert PDF to/from docs
The Recently Opened Files zone: stores a list of files that are most recently opened

Just as the name indicates, the Launch window is only visible once when the application is opened for the first time. After that, all features are accessible from the Main window.

The Main Window

Based on common workflows of working with PDF files, the Main (application) window is conceptually divided into five functional groups: View, Annotate, Convert, Pages, and Documents, each of which offers a group of cohesively related features.

Main functional groups

The Main window is organized into five functional groups (a.k.a. functional modes): View, Annotate, Convert, Pages, and Documents. The View group provides options for viewing and navigating PDF files, while the Annotate group offers tools for highlighting, underlining, and adding notes to specific parts of a document. The Convert group allows users to convert PDFs to other formats, such as Word or Excel, and vice versa. The Pages group offers options for rearranging, rotating, or deleting pages in a PDF file, while the Documents group provides features for organizing and managing multiple PDF files at once.

Switching across the Main functional groups is made easy by clicking one of the five links located at the top-center of the Main window. However, it is important to note that any unsaved changes will need to be saved before jumping to or back to a particular functional group. Specific functions of each group are explained in detail in the sections to follow.

Application toolbars

The toolbars are located in the top area of the main window. There are two groups of toolbars:

The Main toolbar: is located in the top-left corner of the application window and consists of a fixed number of buttons:
- Open
- Save / Save as
- Print
- Undo / Redo
- Help
The Functional group toolbars: vary between the different functional groups to provide features specific to the current group. For instance, the toolbar of the View mode is shown below:

Open, Save, and Print PDF

When you use the “Save As” function, a dialog box will appear asking you to choose a name and location for the new file. The original file will remain unchanged, and the new file will be saved with the name and location you specified.
