Frequently Asked Questions

Find answers to common questions about e-Aadhaar signature verification.

Upload your original digitally signed e-Aadhaar PDF to PixDok's e-Aadhaar Digital Signature Verifier. The tool analyzes the embedded PDF signature and displays the available verification result.
It indicates that the embedded digital signature has passed the applicable signature verification checks. It relates to the digital signature and document integrity, not independent Aadhaar identity authentication.
Yes. You can use a supported mobile browser to upload your original e-Aadhaar PDF and perform the available verification checks.
There are several reasons a PDF signature may not be shown as valid: the PDF has been modified after it was digitally signed, the PDF signature is damaged or incomplete, the certificate cannot be validated, or the file is a scanned copy rather than the original digitally signed PDF.
Usually not. A scanned PDF is generally an image-based copy and may not contain the original cryptographic digital signature. Use the original digitally signed e-Aadhaar PDF whenever possible.
The verifier is designed to minimize exposure of your document. When verification is performed in volatile RAM / browser mode, the PDF is processed without permanent server-side storage.
Yes. A web-based PDF signature verification tool such as PixDok provides an easy alternative for checking supported digitally signed PDFs without requiring Adobe Acrobat installation.
Editing a digitally signed PDF can invalidate its signature or cause the document to show that it has been modified after signing. Always retain the original signed PDF for verification.
No. PixDok's e-Aadhaar Signature Verifier is designed to verify the digital signature embedded in the PDF. Digital signature verification should not be confused with Aadhaar authentication or identity verification.
The original digitally signed PDF contains the cryptographic signature and certificate information required for digital signature verification. A screenshot, photograph, or scanned copy generally does not preserve this information.
All processing is done in volatile memory and never retained on disk. Your Aadhaar document contains sensitive personal information, and PixDok is built with strict privacy-first architecture.
