- Automated OCR rejects application for unreadable scan

Frequently Asked Questions
Q:Why do recruitment portals reject photos taken with mobile cameras?
Government exam portals use automated OCR and document indexing tools. Mobile camera photos often have uneven lighting, dark hand/phone shadows, yellow indoor light tints, or curled desk edges. These make small printed numbers (like roll numbers and mark totals) unreadable by the automated verification systems, leading to application rejection.
Q:What is the difference between "Magic Color" and "High-Contrast Xerox"?
"Magic Color" normalizes the paper background to pure white while preserving the original color of official red/blue rubber stamps, university gold seals, and ink signatures. "High-Contrast Xerox" uses adaptive binarization to turn every character into crisp black ink on stark white paper, perfectly mimicking a high-end office photocopy machine.
Q:Will cleaning the document affect its legal validity?
No. Our engine cleans optical shadows and enhances contrast without altering or interpolating any printed text, numbers, signatures, or seal shapes. It produces a cleaner representation of your original document.
Q:Is it safe to upload sensitive certificates to Kagazo?
Yes, 100% safe. Processing happens exclusively in volatile RAM memory. Documents are never saved to disk, stored in databases, or used for AI training. Everything is automatically destroyed upon download.
