The RPF Constable application form gets rejected for the smallest photo and signature errors, and once the correction window closes there is no fixing it. Lakhs of candidates apply for a limited number of posts every recruitment cycle, so the Railway Recruitment Board does not give you a second chance once your form is submitted with the wrong upload.
Because RPF Constable is recruited through the Railway Recruitment Board's Centralised Employment Notice, the same photo and signature format is reused across most RRB exams, but candidates still get tripped up by the exact KB and cm figures every year. This guide gives you the exact photo and signature specifications for the RPF Constable form, based on the latest RRB CEN notification, so you can get it right the first time and skip the panic of a last-minute re-upload.
Photo Size Requirements
Your photograph for the RPF Constable application must be sized 3.5cm x 4.5cm, the same as a standard passport photo. The file size should fall between 20KB and 50KB (a few RRB CENs have used a slightly different range, so always check the exact figure printed on your specific notification before uploading). The image must be saved in JPG or JPEG format only. Use a plain white or light-colored background, and make sure it is a recent color photograph with no cap, hat, or sunglasses. Your face should be clearly visible and centered, since this photo is matched against you at the exam center and again during document verification. A scanned studio print usually compresses more cleanly to this range than a raw smartphone photo, so if you are struggling to hit the exact KB window, start with a well-lit, uncropped shot rather than trying to fix a bad photo after the fact.
Signature Size Requirements
The signature must be scanned separately from the photo and sized 3.5cm x 1.5cm, with a file size between 10KB and 20KB, saved as JPG or JPEG. Sign with black or blue ink on a plain white sheet of paper, then scan it clearly before cropping to size. Use your normal running signature rather than capital block letters, and make sure it matches what you write on your admit card and at the exam hall, since RPF verification staff compare all three at document checks and at the physical efficiency test stage.
Common Mistakes That Get Applications Rejected
Most RPF Constable rejections trace back to a handful of avoidable errors. Candidates often upload a photo in PNG format or a scanned PDF page instead of JPG, which the portal simply refuses. Others crop their photo to the wrong pixel ratio, stretching or squashing the face. A colored or patterned background, or a photo taken with a cap or sunglasses still on, is another common reason for rejection at the verification stage. Many applicants also upload a blurry phone photo of their signature instead of a proper scan, which gets flagged as unclear, and some simply run out of time compressing a 3MB camera photo down to 50KB and end up submitting a low-quality, over-compressed image instead.
