When you have a large PDF file and want to quickly scan it for the sake of having a digital version of the document, you have two options: you can either split the file into several smaller pieces and store them separately, or you can use the SkanApp.

In the first case, you need to download the SkanApp from the Google Play Store. Once you have it, you will be able to scan the PDF file and save the results as JPEG or PDF. If you need to, you can also edit the document and save it again. In the second case, you need to scan the file using the SkanApp and then upload it to the Cloud. 

The advantage of the second option is that you can use it without installing anything else. Moreover, you will be able to access the file from any device, even from a smartphone or tablet.

In order to use the SkanApp, you need to install it on your device and activate the Bluetooth.
