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 Sarathi Parivahan photo and signature uploads.

What are the exact photo specifications for Sarathi Parivahan Driving Licence?

The Ministry of Road Transport & Highways (MoRTH) requires applicant passport photographs to measure 35 mm × 45 mm (or 413 × 531 pixels at 300 DPI). The file size must be strictly between 20 KB and 50 KB in JPEG/JPG format with a light or white background.

What are the exact signature specifications for Sarathi 4.0 portal?

The signature file must measure 20 mm × 50 mm (or 236 × 591 pixels at 300 DPI) and must strictly be between 10 KB and 20 KB in JPEG/JPG format. Signatures below 10 KB or above 20 KB will be rejected automatically.

Why does the Parivahan portal show "File size is out of bounds"?

Sarathi has an unusually tight threshold for signatures (10 KB to 20 KB). Regular compressors often compress signatures to 8 KB (too small!) or 22 KB (too large!). Kagazo’s binary search engine guarantees the signature lands between 12 KB and 18 KB with 300 DPI JFIF markers embedded.

Can I upload a phone selfie for my driving licence renewal?

Yes. Upload your portrait selfie. Our engine allows you to adjust zoom, center the crop, and straighten the orientation to match standard 35×45 mm passport photo guidelines.

Are my identity files stored or saved anywhere?

No. All resizing, cropping, and quantization occur directly in your browser’s volatile RAM via WebAssembly. Zero files are uploaded to any server.
