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 (1MB Compressor)

Common questions about compressing images to 1MB.

How does Kagazo compress 10MB+ photos to under 1MB without quality loss?

Modern smartphones capture photos at 12MP to 48MP with high redundant color data. Kagazo applies multi-step progressive Lanczos downsampling and optimized JPEG quantization tables, retaining razor-sharp details while shedding 80–90% of unnecessary file weight.

Which portals require images under 1MB?

Passport Seva (address and birth proofs), global visa portals (US, UK, Schengen, Canada), online banking verification systems, and corporate email attachments frequently enforce a strict 1MB ceiling on uploaded image files.

Can I compress iPhone HEIC or PNG images to 1MB JPG?

Yes! Upload your PNG, JPG, JPEG, or WebP photo. Kagazo converts and optimizes the image to a standardized JPEG strictly under 1000KB (1MB) with universal device compatibility.

Are my confidential photos stored or viewed by anyone?

Never. Kagazo processes all files locally in your device’s volatile memory via client-side WebAssembly. No image is ever uploaded to our servers or stored in any database.
