I'm very happy to use SmallPDF as a non-business user as an alternative to a very expensive Adobe account for home use. It is very easy in use and more affordable for home users than its big brother. The programs are very straight forward in use and also their support is very responsive and to the point. I'm very satisfied with their offer/product. Maybe for a lot of home users who does not use these functionalities a lot, a business model with pay per use can be a win-win for both Smallpdf and home users who use the program only a few times a year.
