What it solves
Kindle Cover, without the guesswork
Kindle covers are judged twice: once at full size on the product page, once at roughly 100 pixels in a search result. This tool sets up the ebook proportions and asks you to judge the title at thumbnail size before you export. It produces the cover image; KDP still does the final review, and the numbers here follow KDP's published guidance, which you should confirm before upload.
KDP ebook specs
What Kindle needs from a cover file
These are the values KDP publishes today. Requirements change, so confirm on KDP's official ebook cover page before you upload. This site is not affiliated with Amazon.
Format
JPEG (.jpg/.jpeg) or TIFF (.tif/.tiff). KDP lists 72 DPI and recommends a minimum resolution of 300 PPI.
File size
Under 50 MB. Avoid extra compression — the store re-compresses your image for display.
Color
RGB, no color separation. Covers with very light backgrounds can disappear on the store page — add a narrow mid-gray border.
Ebook cover vs paperback cover
A Kindle cover is a single front image. A KDP paperback cover is one PDF with the back, spine and front plus 0.125 in of bleed, and the spine width changes with page count and paper. Generate the ebook cover here, then use the book cover size calculator for the paperback wrap, or read KDP's paperback cover guide. KDP's own cover calculator is the final word on file size.
Pick ebook or paperback
Choose Kindle ebook for a store image, or KDP paperback to work from a print trim. The two need different files.
Build for the thumbnail
Keep the title short, the contrast high and the subject legible when reduced. Generate one direction and check it small.
Export and verify specs
Export JPEG or TIFF, then confirm pixel size, DPI and file size against KDP's current cover guidelines before you upload.
Use cases

Cover refresh
Test a sharper, high-contrast direction for a backlist ebook without a full redesign.
FAQ
Questions about Kindle Cover
What size should a Kindle ebook cover be?+
KDP's current guidance lists a 1600 × 2560 px cover at 300 DPI, JPEG or TIFF, under 50 MB, with an ideal height/width ratio of 1.6:1. Check KDP's cover guidelines page before upload in case the numbers have changed.
Which file type does Kindle accept?+
KDP currently accepts JPEG and TIFF for ebook covers. The tool can also export a PNG for previews, but use JPEG or TIFF for the upload unless KDP's guidelines say otherwise.
Does this produce the EPUB file too?+
No. It produces the cover image only. You still need to format the interior and build the ebook file in your writing or layout tool.
Can I use the same cover for the paperback?+
Not directly. A paperback needs trim size, spine width and bleed, and the back cover is part of the file. Use the cover calculator with your binding and page count to get those numbers.
Will the cover pass KDP review?+
No tool can promise that. KDP reviews each file, and rejection usually comes from low resolution, wrong proportions, unreadable text or rights issues. Check the specs and the rights for every element before you upload.
Can I upload my own artwork as a reference?+
The Kindle tool starts from a prompt. For a specific character or composition, use the main book cover generator, which accepts one reference image, then size the result for Kindle.
Why does my cover look weak in search results?+
Most likely the title is too small or the subject gets lost when the image is reduced. Regenerate with a bigger type zone and simpler background, then preview at roughly 100 px wide.
Can I change the title after exporting?+
Yes. Edit the title field and generate again, or order the print-ready front cover so the type is set as a clean text layer and late title changes are easy.
Using Kindle Cover Generator well
Describe the final use first: trim size, where the cover will appear, and how much text it has to hold. Generated artwork is a starting point — check the output at full size, replace placeholder text, and confirm the file against KDP's current template before you upload. For print files you also need the rights to every image and font you use.
Runs on the site's shared generation pipeline. Model availability can change without notice.
Sizing the file is a separate job from making the image. The cover size reference lists the full wrap for every common trim, and the cover calculator turns your page count and paper into the spine width before you export.
