FitPDF Pro uses a clear, guided workflow so you always know what comes next. Each step is visible at once, with live status and control.
The main window shows whether you’re using the Free version and provides a simple way to unlock Pro. The interface is organized into clear cards for each step: output settings, PDF selection, and creation status.
Select where your PDFs will be saved and customize the output filename prefix. This ensures your generated files follow your preferred naming convention. Next, move on to adding PDFs in Step 2.
Add PDFs by dragging files into the window or by using the buttons to select individual PDFs or an entire folder. You can drag to reorder files before processing. When ready, click Create PDFs.
Watch real-time progress in the status bar as files are created. For large jobs, you can safely stop processing at any time using the Cancel button.
