Top 4 Reasons Why UPSC Rejects Candidate Uploads:
- File Below Minimum Limit: Candidate files below 20 KB are rejected by the server firewall just like oversized files. Our smart algorithm guarantees output is strictly inside the [20KB, 300KB] range.
- Distorted Facial Aspect Ratio: Stretched or squashed faces caused by improper resizing. Use the Auto-Center Face or Crop tool to keep authentic natural facial proportions.
- Unacceptable Background: Outdoor, shadowed, or colored backgrounds. UPSC requires white paper with black ink.
- Capital Letter Signatures: Signatures in capital block letters are strictly prohibited. Signatures must be executed in running cursive handwriting with black ink on plain white paper.
