You mean like screenshot? Don't do it like that, man. If you buy your raws from Kindle, at least rip it using Calibre to get the actual image files. It's pretty easy and the tutorials are everywhere.
Downscaling bad raws won't do anything good. There's no point doing that. You might as well download public raws from 13dl, LHscans or other raw websites. You'll still get a higher quality raws that way.
