The Scan app is part of both Windows 10 and its successor Windows 11. In Windows 11, only the Scan app is present by default, whereas Windows 10 comes with both Scan and Windows Fax & Scan by default.
One of the benefits of using the Scan app over its predecessor Windows Fax and Scan tool, is that it can save scanned documents and pictures in PDF without using any additional software.
The Scan app does not offer much over the Windows Fax and Scan utility. That said, you get all the basic settings and options required to scan documents and pictures.
Since the Scan app is relatively new, it still has some issues. At times, it fails to detect the scanner. Sometimes, it shows a “could not complete the scan” message during the scan.
If you have been encountering issues with the Scan app, you can consider repairing, resetting, or reinstalling it.
