Why Application Portals Reject Uploaded Files
Online application systems often utilize automated validation servers that reject images failing strict criteria:
- File Size Violations: Image exceeds the maximum KB limit or is smaller than the minimum KB.
- Dimension Mismatch: The photo does not match the exact width and height requirements.
- Background Noise: Signature photo has dark grey background shadows from phone camera capture.
