Kukureku inspects deterministic facts
Page geometry, common metadata, standard forms, XFA presence, and declared capability coverage are analyzed.
Read facts, findings, and coverage
Use CHECKED, ISSUE FOUND, NOT CHECKED, and NOT SUPPORTED to understand exactly what the result means.
Helpful tips
Get the best result
Treat facts and findings separately
Facts are deterministic observations such as page count or field count. Findings explain why an observed fact may deserve attention.
Read the coverage panel
NOT CHECKED and NOT SUPPORTED are intentional trust signals. Kukureku does not turn an uninspected area into a false clean result.
Inspect before destructive work
Page geometry, filled forms, XFA, and metadata can affect what should happen before compression, redaction, flattening, or external sharing.
Frequently asked
Common questions
Does the Inspector modify my PDF?+
No. Unified Document Inspector V1 only reads deterministic document facts. It does not rewrite or download a modified copy.
Does CHECKED mean the PDF is completely safe?+
No. CHECKED means that specific capability was inspected. The coverage panel also shows areas that were not checked or are not supported.
Is my PDF uploaded?+
No. The current Inspector runs locally inside your browser.
