Hey Product Hunt community! 👋 I built **Kagazo** out of a very frustrating problem I kept seeing in India. Every year, millions of students and job applicants submit college applications, government exam forms, scholarships, and other official documents. Yet a surprisingly common issue can cause unnecessary confusion or even rejection: **A perfectly valid government-issued PDF shows “Signature Not Verified” with a yellow question mark.** 😕 This happens because many PDF viewers don’t have India’s **Root Certifying Authority of India (RCAI)** trust chain pre-installed. The document may be cryptographically valid — but the software simply doesn’t recognize the certificate chain. ### 🚀 Meet Kagazo With Kagazo, you can: * 📄 Drop your government PDF directly into the browser * 🔐 Cryptographically validate the digital signature * ✅ Embed the required LTV information and get a clear, verifiable green tick * ⚡ Complete the process in under 2 seconds * 🔒 Keep files private with our **Zero-Storage Architecture** — documents are processed in volatile RAM and are never stored on disk or in a database But document verification is just the beginning. ### 🛠️ 56+ Free Tools for Students & Applicants Kagazo also includes tools designed specifically around the frustrating requirements of Indian applications and exams — including: * Image compressors * Photo resizers * Signature resizers * Aadhaar masking * Declaration/form preparation * PDF utilities * And many more ### 🎯 Built Around Exact Exam Requirements One thing we really wanted to solve is the **“exact file size” problem**. Most generic compression and resizing tools simply reduce a file until it fits. Kagazo is designed differently. When an exam or application asks for something like **20–50 KB, a specific pixel dimension, or a particular format**, our tools are designed to automatically optimize the image while maintaining as much clarity as possible — whether it’s a **photo, signature, or declaration form**. The goal is simple: **Don’t make students keep guessing, compressing, resizing, and re-uploading until the portal finally accepts their file.** We want Kagazo to produce an application-ready file in one go. We’re building Kagazo specifically for the real-world problems students and applicants face while dealing with Indian government portals and applications. I’d genuinely love your feedback. ❤️ **What tools would you like us to build next?** **What’s the most annoying document or application problem you’ve faced?** Try Kagazo and let me know what you think! 🚀
