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 (UK Passport Photo)

Clear answers for British passport online applications and paper counter submissions.

What are the official HM Passport Office photo dimensions and rules?

The photo must measure 35mm wide by 45mm high. The head measurement from the crown of your head to the bottom of your chin must be between 29mm and 34mm (occupying 64% to 75% of the total frame). The background must be plain light grey or cream — NOT pure white.

Why does HM Passport Office reject pure white backgrounds?

Unlike the US, the British HM Passport Office requires a plain light grey or plain cream background. A pure white background causes halo glare on biometric scanners and makes light hair blend into the border.

How do I print 8 UK passport photos for £0.19 instead of £12?

Supermarket photo booths and Snappy Snaps charge £10 to £15 for 4 passport pictures. When you download Kagazo’s 4×6" photo sheet (which tiles 8 identical 35×45mm photos at 300 DPI), you can print it as a standard 4×6 photo print at Tesco, Boots, or Asda for just £0.19 to £0.35!

Can I use this for the online UK passport renewal digital upload?

Yes. Our engine outputs a high-resolution 300 DPI digital JPEG (minimum 600×750 pixels) that satisfies HM Passport Office digital upload gate checks.
