Depending on the complexity of your eBook, the following file formats are supported by Amazon, however, do not confuse "supported" with "recommended" or even viable. As noted below, files containing many images, tables and graphs require more scrutiny prior to making available for sale to the public. Establish a protocol or SRP (Standard Rules of Procedure) early in the process of creating your eBook and you will find that even the most complex files and file formats can be whipped into submission and display exquisitely across a plethora of devices for your reader's pleasure.

KDP: Ideal Book Cover Dimensions For Publishing on Amazon (Design Tips)

Size Matters: An ideal book cover for use with KDP & Amazon.com

Your book cover image should have a height/width ratio of 1.6, which means: 

• A minimum 625 pixels for the shortest side and 1000 pixels for the longest side 
• For optimal quality, your book cover image should be 2820 pixels on the shortest side and 4500 pixels on the longest side 

Amazon accepts two image file types;
1. TIFF, or .tif(f) 
2. JPEG, or .jpeg 

File Compression / Size

Amazon suggests the following:

"KDP applies additional compression to images when displaying them on its website. For best results, images should be uploaded with minimal compression"

Having just done this myself, I converted my book cover image into both JPEG and TIFF formats. Keeping in mind that minimal compression is good I found the .tif / TIFF file was much larger:

TIFF Book Cover File Size: 12.9 Mb

The Exact image saved as a .jpg: 

JPEG Book Cover File Size: 1.1Mb

I'm going with the TIFF file!
