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. ❤️
