wumpus Posted April 26, 2016 Share Posted April 26, 2016 (edited) I scanned a 3.5"x5" pic on a Canon 4200F at 600dpi and outputting as BMP using CanoScan Toolbox (18.104.22.168). I scan to BMP so I can open the image with Paint.net (4.0.9) and Save As JPEG and control the JPEG quality settings (which I can't figure out how to do with the Canon tool). Windows Explorer shows the Horizontal & Vertical Resolution of the original BMP as 600dpi and the JPEG as 599dpi. Any ideas why the JPEG image has reduced resolution? If I scan the pic and output it as JPEG, then use Paint.net to Save As (a different) JPEG, the dpi doesn't change from 600dpi. Even if I modify the image before Save As the dpi doesn't change. Is it normal for Paint.net to change the dpi? Edited April 26, 2016 by wumpus Quote Link to comment Share on other sites More sharing options...
