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 Exact KB Targeting Beats Traditional Quality Sliders

The Problem with Competitors

Tools like TinyPNG, iLovePDF, and Smallpdf only offer vague "Medium" or "Low" settings. If a university portal requires <100KB, you are left guessing and repeating compression 5 times.

Frequently Asked Questions

Everything you need to know about precision image compression.

How does Kagazo compress images to an exact target file size?

Unlike generic online compressors that use arbitrary "Low/Medium/High" quality buttons, Kagazo runs a recursive 7-step quality bisection algorithm directly inside your browser. It calculates the exact JPEG compression matrix required to land within ±1.5 KB of your chosen target size.

Are my images uploaded to any remote server?

No. Your photos, signatures, and documents are processed 100% client-side inside your browser’s volatile memory. Zero bytes leave your device, ensuring total security and privacy.

Can I crop or straighten my photo before compressing?

Yes! Click the "Crop & Frame" button to access the interactive studio viewport. You can pan, pinch-zoom, rotate 90°, or use the fine angle slider (-15° to +15°) to straighten camera photos before compression.

Which image formats are supported?

You can upload JPG, JPEG, PNG, and WebP images up to 30MB in size. The compressed output is formatted in clean, standard JPEG with an RFC-compliant 300 DPI header for universal portal compatibility.

Is there any watermark or subscription fee?

None. Kagazo provides 100% free compression with zero watermarks, no account registration, and no hidden subscriptions.
