Do not rebuild the whole book from one vague message

KDP messages often name a symptom rather than the source. A page-size warning can come from one stray page; a cover warning can come from a page-count change; a processing failure can come from encryption or an invalid export.

Keep the exact message and change one controlled variable at a time.

  • Record the file name and page numbers
  • Confirm the final trim and page count
  • Export a fresh file from the source
  • Compare listing metadata with the actual book

When to ask for a human review

Complex children's books, workbooks, textbooks, and image-heavy interiors often require visual judgment. The assisted option reviews one complex title instead of pretending every layout can be repaired automatically.

FAQ

Frequently asked questions

Why does KDP say my manuscript failed to upload?

Common causes include an unreadable or encrypted file, incorrect page dimensions, margin or bleed conflicts, missing fonts, crop marks, comments, and a damaged export.

Should I rename a failed PDF and upload it again?

No. Re-export from the source application after correcting the cause. Renaming does not repair the PDF structure.

Can ShipMyBook guarantee KDP approval?

No. ShipMyBook can identify and repair many preparation risks, but Amazon controls its review and publishing decisions.

Need the file fixed, not just decoded?

Use a release pass for a text-led title or request assisted review for a complex layout.
