Hi Andreaj,
Sorry for the delay in response.
As you need the service that will help you to convert the Scans and pictures to PDF, you will need Adobe Acrobat DC subscription for that.

Answers to some of the most frequently asked questions about Acrobat DC
I have checked that you have Adobe Export PDF subscription currently.
If you need to buy Adobe Acrobat DC subscription, you will need to first cancel the Adobe Export PDF subscription.
Refer the steps provided here Return, cancel, or exchange an Adobe order to cancel the subscription.
Let us know if you need any help or have any questions.
