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.

The Under-Size Trap: Why Ordinary 20KB Compressors Fail

The Problem

When you crop a signature tightly, it contains very few pixels. Generic tools compress it to 4 KB – 8 KB. When you upload this to SSC, UPSC, or TNPSC, the portal blocks it because it is strictly below the 10 KB minimum.

The Kagazo Solution

Kagazo super-samples the signature at 300 DPI and injects a standard, safe JFIF comment structure that pads the binary size to comfortably sit between 12 KB and 18 KB without degrading visual clarity.

Frequently Asked Questions (20 KB Image Compressor)

Common queries about compressing images to 20 KB.

How do I compress an image to strictly 20 KB without dropping below 10 KB?

Ordinary compressors only shrink images downwards, often turning cropped signatures into 4–8 KB files that get rejected by government exam portals with "File size less than 10 KB". Kagazo is bi-directional: it compresses images over 20 KB and safely pads images under 10 KB, ensuring the output strictly lands in the 12–18 KB safe zone.

Will my signature remain sharp and clear at 20 KB?

Yes. Kagazo applies our Xerox Ink Boost algorithm that washes background paper to pure white (#FFFFFF) while preserving high-contrast dark pen strokes, preventing the blurry pixelation typical of other tools.

Which portals require 10-20 KB files?

Almost all major Indian recruitment and admission portals—including SSC (CGL, CHSL, MTS), TNPSC Group 1, 2, 4, UPSC, IBPS, and State PSCs—mandate signatures to be between 10 KB and 20 KB.

Is this 20 KB compressor completely free?

Yes, 100% free with zero watermarks, zero subscription fees, and no account creation required.
