Left thumb impression resize for IBPS and SBI (240 × 240 px, 20–50 KB)
Short answer: IBPS and SBI forms ask for the left thumb impression as a JPG of 240 × 240 px at 200 DPI (3 × 3 cm), 20 KB to 50 KB, made with black or blue ink on white paper.
Press your thumb on white paper, take a sharp photo from straight above and upload it below: the tool makes the file in exactly this size.

Questions
How do I make the left thumb impression for the IBPS form?
Put black or blue ink on your left thumb (a stamp pad works), press it once on plain white paper without smudging, let it dry and take a photo in daylight from straight above. Upload the photo here and download the 240 × 240 px JPG.
What is the left thumb impression size for IBPS and SBI?
JPG, 240 × 240 pixels at 200 DPI, which is 3 × 3 cm, and a file of 20 KB to 50 KB. The same numbers are in the IBPS PO, Clerk, RRB, SO and SBI PO and Clerk notices; the table below links each exam page.
I do not have a left thumb. What do I upload?
The notices allow the right thumb in that case, and give further rules for other fingers. Read the section on the thumb impression in your own notice before you upload.
My thumb impression is smaller than 20 KB. How do I fix it?
Use the original photo from the camera, not a forwarded copy. If the result is still below 20 KB, the tool adds empty comment bytes inside the JPG to reach 20 KB; the picture does not change.
Do you keep my photo or signature?
No. The picture is processed in memory to make the file and deleted right away. We never save it.
