Ending Form Rejections for Millions of Aspirants
ExactKB was engineered by engineers and competitive exam mentors to solve the most frustrating barrier in online applications: strict, confusing photo and signature upload requirements.
The Aspirant's Frustration
Every year in India, over 40 million candidates submit applications for recruitment and entrance exams including SSC CGL, UPSC CSE, RRB NTPC, NEET, and IBPS.
Unfortunately, over 35% of initial submissions fail automated portal validation due to:
- Photos falling under the 20 KB minimum threshold after standard mobile compression.
- Missing 200 or 300 DPI JFIF binary metadata headers.
- Shadowed, gray paper backgrounds on candidate signatures photographed indoors.
- Inaccurate pixel dimension ratios causing stretched or distorted facial images.
Worse, many legacy resizers spam users with invasive video ads, force subscriptions, or upload private biometric passport photos to unverified third-party cloud servers.
Our Technical Innovation: 100% In-Browser Execution
ExactKB was built on a simple uncompromising principle: your biometric data should never leave your personal computer or phone.
Tests JPEG compression steps in local memory to guarantee files hit exact KB boundaries.
