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

Everything you need to know about Apple HEIC photos and format conversion.

Why does my iPhone take photos in HEIC format instead of JPG?

Starting with iOS 11, Apple adopted the High Efficiency Image Container (HEIC) standard based on HEVC video compression. HEIC photos take up roughly 50% less internal storage than traditional JPEGs while preserving 16-bit dynamic range. However, most government job portals, exam application sites, and Windows systems reject .heic files.

Are my private photos uploaded to your server during conversion?

No. Unlike conventional online converters (such as CloudConvert or iLovePDF) that upload your photos to remote cloud servers, Kagazo uses client-side WebAssembly. All HEIC decoding, color-space mapping, and JPEG quantization execute 100% inside your device’s volatile RAM. Zero bytes are ever sent across the internet.

Can I convert multiple iPhone photos at once?

Yes! You can drag and drop up to 50 Apple HEIC photos simultaneously. Our batch engine processes them smoothly and lets you download all converted JPGs in a single organized ZIP archive with one click.

Can I convert my iPhone HEIC photos directly into a PDF document?

Yes. Simply toggle the output format to "A4 PDF". The engine will automatically compile your photos into a single, clean A4 PDF document ideal for submitting homework, receipts, and government records.

How can I make my iPhone camera shoot in JPG by default?

On your iPhone, open Settings > Camera > Formats and select "Most Compatible" instead of "High Efficiency". This instructs iOS to save future photos directly as universal JPEG files.
