RRB NTPC Upload Rules photo size and signature rules
Photo: CEN-specific; follow the active portal. Signature: CEN-specific; verify exact range. Format: JPG / JPEG. Background: Check the active CEN notice. Fix the file early so a preventable upload error does not cost you the current application window.
Use the built-in fixer on this page
Use the official application camera for the live photo. Use the on-page workflow only for the separately uploaded signature, after checking the active CEN notice.
Why RRB NTPC Upload Rules uploads get rejected
Live photo capture is rejected
Do not compress or upload an old photo for this step. Use the official application camera flow and retake the preview if the portal rejects it.
Open official portalWrong 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.
Open CEN signature toolDimensions or framing look wrong
Use an exact-dimension fixer if the portal expects a passport-style or exam-specific crop.

Current-cycle checklist
- 1. Confirm the live requirement. Use this page as the current-cycle checklist before you open the official portal.
- 2. Fix the file early. Do not wait until the last day to compress, convert, or resize your photo and signature.
- 3. Recheck before submit. Validate the final file once more after every change so the upload passes on the first try.
