RRB Railway Photo & Signature Resizer

RRB photo and signature requirements

Railway Recruitment Boards conduct large exams such as NTPC, Level 1 (Group D), ALP and JE through regional websites and a common application portal. The application asks for a recent colour photograph and signature within set pixel and KB limits, and some cycles have also required a separate SC/ST certificate upload for free travel authority. RRB is strict about photo quality because it is matched at the exam centre and during document verification.

The dimensions, file size range, format and DPI shown in the tool come from our admin-maintained preset for Railway Recruitment Board exams (NTPC, Group D/Level 1, ALP, JE and others), together with the date they were last checked and a link to the official website. Requirements can change with every notification, so compare them with the notification for your exam cycle before uploading. If a value differs, pick the custom option in the exam resizer or tell us through the contact page so we can update the preset.

How the resizer meets every rule

• Exact pixels: the image is cropped to the required shape and resized to the exact width and height, never stretched.
• KB range: the tool finds the highest JPEG quality under the maximum; if the result is below the minimum, it adds harmless padding bytes so the portal accepts it.
• Portal-safe sizes: the maximum is treated as 1,000-byte kilobytes and the minimum as 1,024-byte kilobytes, so the file passes whichever definition the site uses.
• DPI: written into the file when the preset specifies it.

Photo tips that prevent rejection

• Recent colour photo, face centred, both ears visible where possible, neutral expression.
• Plain light background, even light, no shadows, no caps or dark glasses.
• Don’t upload a photo of a printed photo or a selfie with a tilted head.

RRB-specific tips

RRB has rejected applications for unclear photos, photos with caps or glasses, and signatures written in capital letters. Keep your face clearly visible and sign normally. Save the final files, because railway exams often run in several stages over many months and you may need to recognise the exact photo you submitted.
