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 about Full HD background removal.

01.Why does Kagazo not limit downloads to 500px like other websites?

Most commercial background removal tools run heavy cloud servers and intentionally downscale your image to 0.25 megapixels (500×500 px) to force you into paying subscription fees or buying credits for "HD" downloads. Kagazo processes your image entirely inside your own device’s browser memory via WebAssembly and HTML5 Canvas, eliminating server compute costs and letting us offer 100% full original resolution for free.

02.Can I replace the removed background with white or passport blue?

Yes! You can choose between Transparent PNG, Official Passport Pure White (#FFFFFF), Passport Light Blue (#B0C4DE), Light Grey, or any custom color using the built-in color picker. JPG outputs automatically include binary 300 DPI headers for government passport submission.

03.Can I batch remove backgrounds from multiple photos at once?

Yes. You can select or drag up to 20 images simultaneously. Our batch engine processes all photos with your preferred sensitivity and background settings, and allows you to download them individually or as a single ZIP archive.

04.Are my private photos uploaded to any external server?

Never. Kagazo guarantees 100% In-Browser Privacy. Every pixel calculation, color segmentation, and alpha feathering step executes locally in your browser’s volatile RAM. No images are sent over the internet or logged.

05.How do I fine-tune the edges if stray background colors remain?

Use the "Background Sensitivity" slider in the studio controls. Increase the slider if traces of background remain around hair or shoulders, or decrease it if clothing edges are getting clipped.
