Validador de Arquivos PDF para Amazon KDP
Evite erros e rejeições no upload do KDP verificando antecipadamente as especificações técnicas.
Free KDP File Validator
Pre-flight your interior PDF against Amazon KDP's requirements — trim size, page count, consistency, and file limits — before you upload.
This validator covers the structural checks KDP enforces at upload (dimensions, page counts, encryption). It can't verify font embedding or image DPI from the browser — KDP's own previewer flags those after upload, so always review the online proof.

Frequently Asked Questions
Does this guarantee KDP will accept my file?
No — it checks the structural rules KDP enforces at upload (trim size, page count, consistency, encryption), but KDP's own online previewer performs additional checks like font embedding and image resolution after upload.
What if my trim size doesn't match a standard KDP size?
KDP allows custom trims within its supported range — the validator will warn rather than fail, since custom sizes are valid but ship slightly slower.
Why does it flag an odd page count?
KDP automatically adds a blank final page to make an odd page count even — the validator flags it so you can add your own final page if you want control over what's there.
