Common Mistakes When Uploading Signature
Avoid these common errors to prevent your application from being rejected at the document verification stage.
Blurry Image
Using a low-quality camera or poor lighting makes ink strokes unreadable.
Extra White Space
Not cropping the image properly makes the actual signature appear tiny.
Wrong Format
Uploading PNG or WebP when the portal strictly requires JPEG/JPG.
Ruling/Lines
Signing on ruled paper instead of plain white unruled paper.
