Blu-Ray Backup

Been trying to compress a 50gb blu-ray to 25gb disc. someone recommended DVDFab but i've been reading some reviews that the compression dvdfab does to the blu-ray is not always very good?

anyone have experience with this software? other recommendations?

i also have MakeMKV and Handbrake but all i need to know is the best way to compress the main film on the blu-ray to fit on a 25gb disc with as little loss of quality as possible.

tips?

i dont know how to use handbrake other than the usual presets like "apple tv 3" or whatever. and that compresses the video down considerably because the movie will go from a 25gb file to a 6gb file.

what i want is to just copy the movie from one disc to the other with as little compression as possible.

if i rip the film with MakeMKV is there a handbrake setting that lets me compress the file as little as possible so it will fit on a 25GB disc?

i dont have any ulterior motives. my question was simple. I wanted to know if anyone here uses DVDFab for compression and if they recommend it.

if you're suggesting im making illegal copies of movies i'm not. i own a physical copy of the movie i'm trying to copy, but i dont like lending out my original movies to friends as i never ever ever get them back.

i dont think i need to go into a whole explanation... i just wanted simple helpful advice.
