Is there a way to change the dpi of an imported image?

Recommended Posts



I've created a book cover for upload to Amazon's kindle site, however they want the image at 300 dpi....


The images I used for my project were created with "Logo Creator"  and it exported them at 72 dpi...Is there a way to change the dpi density?

Press ctrl+R. In the window that appears, there is an option to change the resolution of your image.

No, Paint.NET is not spyware...but, installing it is an IQ test. ~BoltBait

DPI only works with printers.


Amazon want you to provide an image 1600 x 1000 pixels for your Kindle cover.  This is the only size you need be concerned with, so make your canvas that size and you'll be OK.

Paint.NET uses the specified DPI to estimate the print size.  That is all. Changing the DPI will not alter the image size (which is expressed in pixels).


Requirements for the size of your cover art have an ideal height/width ration of 1.6, this means: 

• A minimum of 625 pixels on the shortest side and 1000 pixels on the longest side 
• For best quality, your image would be 1563 pixels on the shortest side and 2500 pixels on the longest side

Nowhere does it mention DPI.  Save yourself the effort and just make the cover image 1000x1600 (ratio of 1.6).  This size is specifically mentioned in the detailed KDP guide.
