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 regarding USCIS and US Visa photo compliance.

What are the official USCIS and US Visa photo requirements?

The US Department of State and USCIS require photos to be exactly 2 × 2 inches (51 × 51 mm) or 600 × 600 pixels in digital format at 300 DPI. The subject’s head (from chin to crown) must measure between 50% and 69% of the total image height (1 to 1-3/8 inches). Eye height must be between 56% and 69% from the bottom edge.

Are eyeglasses allowed in US visa or passport photos?

No. As of November 1, 2016, eyeglasses are strictly prohibited in US passport and visa photos, even if you wear them daily. The only rare exception is a signed medical statement in cases of recent eye surgery.

What is the maximum file size allowed for online DS-160 upload?

The official US Department of State online portal requires JPEG files to be less than or equal to 240 KB (kilobytes) and greater than or equal to 60 KB. Kagazo’s binary search engine automatically compresses the photo to between 120 KB and 180 KB, safely within the acceptable window.

How does the 4×6" printable sheet save money at CVS or Walgreens?

Pharmacy photo counters (CVS, Walgreens, Rite Aid) charge $17.99 to $19.99 for two 2×2" passport photos. If you bring a standard 4×6" photo containing six 2×2" pictures, you can print it as an ordinary 4×6 snapshot for approximately $0.35 to $0.40 and simply cut the photos out along the guide lines.

Are my photos uploaded to any remote server or stored in the cloud?

No. All biometric verification, oval alignment, JFIF DPI header injection, and 4×6 sheet rendering take place 100% locally in your browser’s volatile RAM. Your photos are never uploaded or saved.
