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 (10MB PDF Compressor)

Learn how Kagazo compresses large multi-page PDF documents to under 10MB.

Why compress a large PDF down to 10MB?

Many cloud services, enterprise HR systems, client portals, and collaboration platforms enforce a hard 10MB or 15MB file cap. Compressing 50MB–200MB PDFs to strictly under 10MB makes them shareable across Slack, Teams, and web portals without triggering upload rejections.

Will architectural blueprints, CAD diagrams, or financial spreadsheets stay legible?

Yes. Kagazo never rasterizes vector line work, text glyphs, or tabular data. Only bulky embedded photography and scanner raster layers are optimized using multi-step Lanczos resampling, preserving crisp vector lines and fine table borders.

How much compression can I achieve on a 100MB+ scanned book or catalog?

Scanned books and multi-page catalogs typically drop by 70% to 90% in size because default scanner software saves uncompressed bitmaps. By deduplicating repeated background objects and recompressing image streams with modern Huffman-encoded JPEG, Kagazo reliably reduces heavy 100MB+ documents to under 10MB.

Can I select and exclude specific pages before compressing?

Yes! Kagazo includes an interactive Page Selector. Simply click "Select Pages" after uploading your document to preview all pages and exclude redundant cover pages, index sheets, or blank pages.
