KDP tools for authors
Publish on KDP for free
How to publish on Amazon KDP for free, step by step.
KDP charges no upload fee — the costs hide in formatting, covers, and rejected uploads. This guide walks the free path and where the paid boundary actually is.
Checked:
The free path, in order
1. Finish a manuscript in DOCX with clean heading styles. 2. Check the structure with a free preflight so KDP does not reject it at upload. 3. Build the cover with correct spine and bleed for your trim and page count. 4. Write metadata: title, subtitle, description, seven keywords, two categories. 5. Upload, answer the AI disclosure honestly, and set the price.
Every step has a free option: Kindle Create and Reedsy Studio format for free, and ShipMyBook's checks are free before any payment.
The paid boundary is repair, not publication
Free tools are enough until something fails: a cover built for the wrong page count, an EPUB that fails validation, a manuscript full of hidden formatting. Paying makes sense when it fixes a specific failure, not as a subscription to keep.
That is the honest boundary: free checks stay free, and payment appears only when files need producing.
The disclosure question at step five
KDP asks whether content is AI-generated or AI-assisted. Answer honestly per part — text, images, translation. The answer shows on the detail page, and undisclosed AI content is what risks the account.
FAQ
Frequently asked questions
Does Amazon charge to publish on KDP?
No upload fee. Amazon earns through royalties on sales and optional ads. Printing costs are deducted per copy sold, not upfront.
Can I publish for free with a $0 budget?
Yes: free editors for formatting, free checkers for validation, a simple cover from free tools, and no ad spend. The budget question is time, not money.
What is the most common free-path failure?
The cover built before the final page count. The spine width changes with pagination, so build the cover geometry last, after the interior is locked.
