Basically I'm searching for an alternative to Google PDF Viewer that actually is the only capable of handling files of 15.000 pages of jpgs and 4-5 GB of size.
The only problem with the google one is that it doesn't even handle the bookmarks, don't have option on visualizing modes and doesn't have a go to page!
I'm open to other options even paid ones - note: Pay once not subscription models.
I don't need any edits.. just a powerful optimized reader with bookmarks and minor other functions and performance tweaking..
But it should be a program written without any extra permissions, no ads, no malware, adware or anything bad in mind, a program written by a person who intends to even earn money from it but once it is sold the program is your and just works.
