Every year, lakhs of candidates face rejection during online form submission simply because their photo or signature doesn't meet the required specifications. This guide covers exact requirements for all major government exams and how to get it right the first time.
Government exam portals like UPSC's OTRP, SSC's online portal, and railway recruitment boards use automated systems to verify uploaded images. If the dimensions, file size, or format is incorrect, the system either rejects the upload or raises a discrepancy notice later — sometimes after the form is submitted.
Getting this wrong can lead to:

|---|---|---|---|
| UPSC CSE | 3.5×4.5 cm | JPEG | 4 KB–300 KB |
| SSC CGL / CHSL | 3.5×4.5 cm | JPEG | 20–50 KB |
| RRB NTPC | 3.5×4.5 cm | JPEG | 15–40 KB |

Many government and bank exam forms — UPSC, SSC, IBPS, SBI, RBI, LIC and several state PSCs — ask you to upload a single image that has both your photo and signature merged together (instead of two separate files). Use our free Photo and Signature Merge tool to do this in seconds:
No data is uploaded to any server — all photo and signature merge processing happens in your browser, so your documents stay private.
The merged image makes verification faster — the examiner can match your face and signature at once. Most exams that ask for a merged photo + signature specify dimensions in the range of 3.5×6 cm (photo on top, signature below) with file size between 20 KB and 50 KB, JPEG format.
White or off-white background is standard for all government exams in India. Some exams like UPSC explicitly state "plain light background." Avoid patterned or coloured backgrounds.
Yes. You can use our Image Resizer tool directly from your phone. It works on all modern mobile browsers without any app installation.
Your signature at the examination centre will be compared with the one on the form. Try to maintain a consistent signature. If your signatures vary significantly, the authorities may flag it during verification.
