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 (100KB Compressor)

Answers to common questions about 100KB image sizing.

Why do so many job portals and university applications require images under 100KB?

Portals set a 100KB ceiling to prevent database congestion when handling millions of candidate profiles. Uploading an uncompressed 5MB smartphone photo will either cause an upload error ("File size exceeds 100KB") or crash the form submission.

Will my face or resume photo look blurry at 100KB?

Not with Kagazo. 100KB is plenty of data for a portrait or ID photo when properly encoded. We use progressive multi-step downsampling and 4:4:4 chroma preservation to ensure faces, eyes, and text stay crisp and professional.

How do I compress an image to 100KB on my phone?

Simply open this page on your iPhone or Android mobile browser, tap "Upload Image", select your photo from your photo library or camera, and click "Compress Image". In less than a second, your 100KB image is ready to download.

Can I compress multiple images to 100KB?

Yes! You can compress multiple images one by one for free. If you have large batches of 20 to 50 files, our Pro tier unlocks simultaneous one-click batch compression.

Is this 100KB tool safe for confidential ID photos?

Yes, 100% safe. Processing happens directly in your browser using local WebAssembly. Your photos are never sent to a cloud server or saved on external storage.
