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 (5MB PDF Compressor)

Clear answers on compressing heavy multi-page documents to 5MB.

Why do universities and tender portals enforce a 5MB limit on PDFs?

Academic repositories (like Shodhganga, ProQuest, and university submission portals) and government e-procurement systems (like GeM and state tender boards) mandate a 5MB maximum file size per annexure to ensure server stability and swift archiving of thousands of submissions.

Will high-resolution graphs, tables, and color diagrams remain sharp?

Yes. Kagazo separates vector charts and typography from raster backgrounds. Vector paths and text streams remain 100% lossless, while raster graphics undergo intelligent Lanczos downsampling to fit snugly under 5000KB without blurring critical academic data.

How do I compress a 50+ page dissertation or thesis down to 5MB?

Upload your multi-page PDF. Kagazo immediately analyzes stream sizes and recompresses embedded scanned images. If your document still exceeds 5MB due to hundreds of color photos, enabling our "Greyscale Conversion" toggle strips redundant color channels for an immediate 40% file size reduction.

Are sensitive research papers, patents, and medical records safe?

Completely secure. All processing runs in volatile RAM memory. Your files are never stored on permanent hard drives, shared with AI trainers, or accessible to anyone else.
