If your goal is print-ready KDP files (front + spine + back), the “best tool” depends on whether you need:
- Correct dimensions (trim, bleed, spine width)
- Print-safe guides (safe zones, barcode area)
- A workflow that prevents common upload issues before they happen
Quick decision
- Choose Canva if you mainly need fast social graphics and front-only layouts.
- Choose a KDP-focused tool if you publish paperbacks/hardcovers and want fewer rejections.
