Common Photo and Signature Upload Errors

The problem

When an upload fails, portals rarely show a detailed reason. The same file may fail for format (JPEG vs PNG), encoded file size, pixel dimensions, face coverage rules, or a blurred scan. Candidates often retry the identical file multiple times instead of fixing the underlying issue.

Step-by-step

1. Re-read the notification PDF for file format, KB range, and pixel or cm dimensions for both photo and signature.
2. Right-click the file on your computer and confirm actual size in KB — not just the name.
3. For “invalid image format”, re-export as JPEG from a proper editor; do not only rename the extension.
4. For signature errors, re-scan on plain white paper, crop margins, and use Resize Signature at the stated KB cap.
5. For photo errors, verify aspect ratio with Resize Image, then apply the correct 20/50/100 KB tool for that portal.

Common mistakes

• Retrying upload without changing the file.
• Using WhatsApp-forwarded images that were re-compressed and stripped of metadata incorrectly.
• Mixing up photo and signature size limits from different sections of the notification.
• Ignoring a separate live-photo capture step on newer UPSC forms after uploading a static JPEG.
