Hi newbie here, I received my paperwhite today. I'd bookmarked this forum and the day has come. I managed to sneak few pdfs into kindle via USB. I was wondering if you could share with me your methods and workaround for certain problems.
1) pdf quality in paperwhite is agonizing, i converted them to epub and pages would either show low quality images or some random ascii texts for equations
2) I remember seeing a pdf splitter that splits one page into 2, maybe I could boost pdf quality by this way by skipping the entire conversion to mobi ordeal. I'm planning to convert files on pc, is there a suitable software or online tool that can help this?
3) Is there a sync server which is not linked to amazon, where you can upload files in server and sync it to kindle? Or is there a way to transfer files via WIFI from calibre to kindle? Or is there any other method that uses wifi to transfer files from pc to kindle?
I appreciate your time, thank you
