Why does my government PDF show a yellow question mark?

Indian government PDFs are digitally signed using certificates from NIC, eMudhra, or other CCA India licensed authorities. Adobe Acrobat and most PDF viewers don't include India's Root Certifying Authority (RCAI) in their default trusted certificate store. So even though the signature is completely valid and legally recognised under the Information Technology Act 2000, your PDF viewer shows a yellow question mark because it cannot automatically verify the issuer. Kagazo checks your PDF against the actual CCA India trust hierarchy and gives you a copy with a permanent green tick visible on any device.

Is my document safe? Do you store my PDF?

Your PDF is processed entirely in memory during verification. We never write your file to disk, never store it on our servers, and never share it with any third party. The file is deleted from memory immediately after verification is complete. You can also verify this by checking our open source backend code.

Which documents does Kagazo support?

Kagazo supports any PDF digitally signed under India's CCA certificate hierarchy. This includes e-Aadhaar, PAN card, DigiLocker documents, ITR-V, Form 16, and all state government certificates from Tamil Nadu e-District, AP and Telangana MeeSeva, Karnataka Nadakacheri and eJanma, Kerala Sevana portal, and more.

My Aadhaar PDF is password protected. Will it work?

Yes. Enter your Aadhaar password (first four letters of your name in capital letters followed by your birth year, for example RAMA1995) in the password field that appears after you upload your e-Aadhaar PDF. We decrypt it in memory, verify the signature, and return a verified copy.

What is the difference between "Signature Valid" and "Signature Unknown"?

Signature Valid means the document is genuinely issued by the government authority and has not been modified. Signature Unknown means your PDF viewer cannot verify the certificate chain — this is a viewer configuration issue, not a problem with your document. Signature Invalid means the document may have been tampered with or re-saved after signing.

Does this work on mobile?

Yes. Kagazo is fully mobile responsive and works on any Android or iOS browser. No app installation required. Simply open kagazo.in on your phone browser, upload your PDF and verify instantly.

Frequently Asked Questions

Frequently asked questions about signing PDF files online.

Are electronic signatures created on Kagazo legally valid?

Yes. Electronic signatures created by drawing or embedding your signature onto documents are legally recognized in India under the Information Technology Act (IT Act 2000 Section 5) and in the United States under the ESIGN Act (Electronic Signatures in Global and National Commerce Act), as well as the Uniform Electronic Transactions Act (UETA).

Are my confidential contracts or legal documents uploaded to your servers?

Never. Kagazo processes PDF documents and signatures 100% inside your web browser’s volatile RAM using client-side JavaScript (pdf-lib). Zero bytes leave your device, meaning confidential business agreements, tax forms, and rental contracts remain completely private.

Can I upload a smartphone photo of my signature on paper?

Yes! Choose the "Phone Scan" tab and upload a picture of your signature taken on white paper. Kagazo’s thresholding engine automatically removes shadows and paper texture, converting it into a clean, transparent ink signature that blends naturally onto the document.

Is there a limit on how many PDFs I can sign, or are there hidden watermarks?

There are zero limits, zero paywalls, and zero watermarks. While commercial platforms like Smallpdf and DocuSign limit free users to 1 document or slap large branding across your pages, Kagazo is completely free and unwatermarked.

Can I choose which page of a multi-page PDF document to sign?

Yes. Our document navigation toolbar allows you to jump to any page (e.g. Page 3 of 10) and place your signature, date stamp, or initials at the exact line or box required.
