Is it at all possible to download my own PDFs from icloud to my pc?!

Hi Everyone!!

is it at all possible to download my own PDFs from icloud to my pc?! if yes how??? it seems when i open a pdf on iphone and then move it to ibooks, it gets uploaded to and saved in iCloud and can only be either read on iPhone/iPad/Mac or be completely deleted!!!

Also, if i deactivate icloud for ibooks on my iphone (because i dont want all my pdfs automatically uploaded to icloud), all the pdfs there get deleted from icloud and are no longer available on any device, which is very bad because it isn't possible to save them to my pc before they are deleted from icloud (or before the deactivation of icloud for ibooks)

Any help is appreciated!!

Thanks.
