1. How to Open a PDF
There are two possible ways to open PDFs to Windows applications:
- Drag any PDF file from your drive and drop it to UPDF.
- The second way is to import a PDF file by clicking on the Open File button.
2. Open a Locked PDF
You can also open password-protected PDFs on UPDF. While opening a password-protected PDF, UPDF will ask to enter the password. Simply enter the password to gain access to your PDF.
