Conclusions and alternatives

As we can see, Slim PDF Reader is an interesting option if we are looking for a simple, minimalist, free PDF document reader that takes up little space on our hard drive.

Despite the fact that its interface is in English, it is easy to use since the icons of its different buttons and options are quite graphic, although they cannot be organized. Despite taking up very little space on the hard drive, the truth is that when loading documents that are heavy and have many images and graphics, the program uses somewhat high memory.

In addition, it has fewer functions than other similar programs, so it will also depend on whether we are really going to need them.

In the event that it does not meet our expectations, we should know that we can find other free programs on the Internet that we can use as alternatives and that it may be of great interest to us to learn about them.
