What size does an Amazon KDP ebook cover need to be?

KDP recommends 2560 pixels tall by 1600 pixels wide, a 1.6:1 height-to-width ratio, and accepts a minimum of 1000x625 pixels at the same ratio. This tool offers both sizes plus a larger 2000x3200 option.

Does the cover need to be JPG or PNG?

KDP accepts JPEG or TIFF for ebook covers. This tool exports JPG, which matches KDP's preferred format; PNG is also offered for other ebook stores that accept it.

Why can't my cover have transparency?

An ebook cover is a single flat image with no gaps, so any transparent pixels in your source file need to be filled with a background color before export. Pick a color and this tool flattens it for you.

My image is smaller than 1000x625 pixels. Can I still use it?

You can, but the tool will need to stretch it to reach the minimum size, which makes it look soft. For a sharp cover, start with a source image that is at least 1000x625 pixels, ideally 1600x2560 or larger.

Is this only for Amazon KDP?

The 1.6:1 ratio and 1600x2560 recommended size match what most ebook retailers ask for, including Kindle and several other self-publishing platforms, so a cover exported here works beyond just KDP.

Does this upload my cover anywhere?

No. The crop, resize, and background flattening all happen in your browser using the canvas API. Your image is never sent to a server.
