Official answers to common RRB photo upload questions.
Railway Recruitment Board (RRB) receives crores of applications every cycle and uses automated systems to validate uploaded images. The most common rejection triggers are: file size outside the 20-50 KB window (even 51 KB causes rejection), non-white backgrounds, dimensions not matching 320×240 pixels, and signatures written in blue ink or capital letters. A dedicated Railway photo resizer that enforces exact pixel and KB requirements eliminates these technical rejections before you click submit.
The unified rrbapply.gov.in portal is now used for all RRB exams including NTPC CEN-05/2024, CEN-06/2024, Group D CEN-08/2024, and ALP CEN-01/2025. Once uploaded, your photo and signature are validated instantly by the portal. Always target 40-45 KB for photos to stay safely within the 20-50 KB limit, and aim for 38-42 KB for signatures within the 30-49 KB range.
Sign your full name on a plain white sheet using a black ballpoint or gel pen in running/cursive style. Scan at 100 DPI minimum, crop tightly, and import into this tool. Select the "RRB Official 140×60" preset, set target size to 40 KB, and confirm all compliance ticks are green. Signatures in capital letters, blue ink, or with smudges are the most frequent cause of RRB application rejection.
RRB has standardised photo and signature requirements across all exam categories for 2026-27. The same correctly prepared photo (320×240px, 20-50 KB, white background, JPEG) can be used for any of these exams. Only RPF/RPSF has a slightly wider size range of up to 70 KB. Always verify with the CEN notification PDF specific to your exam.
