Why RRB NTPC 2026 uploads get rejected
Photo exceeds 20KB - 50KB
Phone photos are usually far larger than exam upload limits. Use a target-size compressor instead of retrying the same file.
Compress photoWrong format instead of JPG / JPEG
Many apps save images as PNG or WebP. Convert to JPG before the final upload.
Convert to JPGSignature not within the allowed limit
Scanned signatures often include too much blank space and exceed the portal limit.
Fix signatureDimensions or framing look wrong
Use an exact-dimension fixer if the portal expects a passport-style or exam-specific crop.
