GreenTika
Adobe may not automatically verify Indian government PDFs — it needs a full Acrobat installation and complex settings. We verify them properly: e-Aadhaar, e-PAN, ITR-V, DigiLocker, all inside your browser.
Chaosmeld
Four simultaneous minigames — Runner, Miner, Sorter, Defender — sharing one Chaos Meter. Fail any one, chaos spreads everywhere. Survive as long as you can.

CropKaro — Smart ID Card Cropping for PVC Printing
Every PVC card printer in India needs the ID card image at exactly CR80 size: 85.6 mm × 54 mm at 300 DPI (1012 × 638 pixels). But e-Aadhaar PDFs, PAN card PDFs, and Ayushman Bharat PM-JAY cards embed the card at arbitrary sizes within the page — making manual cropping tedious and imprecise. CropKaro uses smart auto-detection to locate the card region in any PDF layout and crop it to the exact PVC size in one click. It supports 10+ Indian government ID card types including Aadhaar, PAN, PM-JAY, Voter ID, ABHA, e-Shram, Driving Licence, and more. 100% browser-based — your file never leaves your device. Free, no sign-up.
GreenTika — Verify DSC-Signed Indian Government PDFs
Millions of Indians download e-Aadhaar, e-PAN, ITR-V, and DigiLocker documents every year — and most see "Signature Validity Unknown" in Adobe Acrobat because Adobe may not automatically verify these PDFs without complex manual settings. GreenTika solves this by performing full PKCS#7 digital signature verification with the CCA India certificate chain, entirely in your browser. Supports both RSA and ECDSA signatures. Your PDF never leaves your device. It works with e-Aadhaar, e-PAN card, ITR-V, Form 26AS, court orders, and any DSC-signed Indian government PDF. Free, no sign-up, no uploads.
