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.

Why 300 DPI Resolution is Essential for Indian Exam Portals

Standard Web Converters (72 DPI)

Most free web tools render PDFs at default 72 DPI screen resolution. When uploaded to government portals, small serial numbers, QR codes, and sub-registrar signatures become pixelated and unreadable, causing application rejections.

Kagazo Engine (300 DPI Official Scan)

Kagazo renders pages at a full 2480 × 3509 pixels (standard 300 DPI print-ready resolution). Every watermark, signature stroke, and barcode remains tack-sharp.

Frequently Asked Questions (PDF to Image Converter)

Everything you need to know about extracting high-resolution images from PDF files.

Why do exam portals require 300 DPI images instead of PDFs?

Certain recruitment and admission portals (such as specific state police recruitments, teacher recruitment boards, and bank portals) only have image upload fields (JPG/JPEG) for identity cards and educational certificates, rejecting PDF files. Extracting at 300 DPI ensures all micro-text, serial numbers, and signatures remain 100% legible.

How do I convert my e-Aadhaar PDF into a JPG image?

Upload your e-Aadhaar PDF into the Kagazo upload box, select 300 DPI and JPEG format, and click "Extract 300 DPI Images". You can preview the extracted high-resolution image with our clarity loupe and download it immediately.

Will converting a multi-page PDF generate images for all pages?

Yes! Kagazo converts all pages of your PDF document. You can preview each page individually using the tab selector and download individual pages or batch-download all pages in one click.

Are my confidential identity PDFs stored on your server?

Never. Kagazo operates entirely in ephemeral volatile memory (RAM). Your PDF and the extracted images are immediately wiped once downloaded. We never save files to disk or databases.
