NDA form rejections are frustrating because the portal error messages are vague. The most common reason is attire — NDA requires formal wear in the photo, no uniform, no casuals. The second most common is the triple signature not being prepared correctly: three signatures on white A4 paper, scanned into a single JPEG, not three separate files. NDA uses the UPSC OTR (One Time Registration) portal, so the photo specs are very similar to UPSC Civil Services. File size limit is generous at 300KB. This page's tool is pre-set to 50KB for NDA — clear quality, well within the limit.

Why Is My NDA & NA Exam Photo Getting Rejected?

The portal runs automated checks. These are the common rejection reasons with exact fixes:

❌ Single signature
UPSC OTR requires 3 signatures in one file. Single = rejected. Fix: Sign 3 times on white A4, scan together, compress as one JPEG
❌ Photo under 20KB
Too small for UPSC portal. Fix: Tool targets 50KB — well above 20KB minimum
❌ PNG format
UPSC rejects PNG. Fix: Tool auto-converts PNG → JPEG
❌ Informal attire
NDA requires formal attire at document verification. Fix: Plain shirt, no casual clothes, no uniform in photo
❌ File named wrong
Signature file must be named signature.jpg exactly. Fix: Rename to signature.jpg before uploading
❌ Dark or patterned bg
White or light plain background required. Fix: Retake against plain white or light wall
❌ Photo over 300KB
Too large. Fix: Tool compresses to 50KB — well within limit
❌ Old photo
Recent photo required. Fix: Take fresh passport photo before applying
