Frequently Asked Questions
Official banking notifications (IBPS & SBI) mandate the LEFT thumb impression. If a candidate does not have a left thumb, they may use their right thumb and note it in their application per official rules.
Yes. Both blue ink and black ink stamp pads are fully accepted by IBPS, SBI, and SSC. However, ensure the ink is not smudged or excessive, as individual fingerprint ridges must remain clearly distinguishable.
The official dimension is 240 × 240 pixels (or 3 cm × 3 cm), format must be JPG/JPEG, and file size must be strictly between 20 KB and 50 KB. Our tool formats to these exact parameters.
If your stamp is excessively smudged with solid ink patches, it is best to take a fresh, light impression on white paper using an ink pad. Then upload the photo to our tool to remove shadows and enhance ridge contrast.
