PDF signature validity unknown fix India
If a PDF viewer says signature validity unknown, GreenTick PDF can check supported Indian digitally signed PDFs and show whether the document is eligible for a green tick print copy.
GreenTick PDF is independent. It is not Adobe, UIDAI, GST, Udyam, MCA, or a government portal.
Why validity is unknown
The viewer may not have the right certificate trust settings, or it may not fully validate the signed PDF structure.
What GreenTick reports
The verification result separates document integrity, signature status, trusted certificate, and output readiness.
Questions
Can validity unknown be fixed online?
It can be verified online for supported documents. The green tick output is generated only if the signature passes checks.
What if my certificate is untrusted?
GreenTick PDF blocks green tick output and shows the failure reason.
