Questions
What size should a thumb impression be for IBPS and SBI?
IBPS (PO, Clerk, SO, RRB), SBI, NABARD, LIC AAO, NIACL, SEBI and RBI Assistant ask for 240×240 pixels (3×3 cm at 200 DPI) in JPEG, between 20 and 50 KB. Pick that size above, or type the size from your own notification.
Which thumb should I use?
Your left thumb, unless your exam says otherwise. If you have no left thumb, IBPS and SBI accept the right thumb, and IBPS then allows a finger or the left toe, named on the image. AFCAT and ICAR AIEEA PG ask men for the left thumb and women for the right.
How do I take a clear thumb impression?
Press your thumb on a blue or black stamp pad, then press it once on plain white paper without sliding. Photograph it in daylight from straight above, with no shadow over the print. Smudged or blurred impressions get rejected.
The ridges disappeared or the print is a black blob. What do I do?
Move the ink threshold slider left to remove smudges and thin a heavy print, or right to keep faint ridges. If your form accepts blue ink, untick the clean-up and the tool only crops, resizes and compresses the photo.
NEET PG asks for a horizontal thumb print. How?
NEET PG, NEET MDS, NEET SS, FMGE and GPAT want the left thumb lying sideways in a 3.5×1.5 cm box: 276×118 pixels, up to 79 KB. Press your thumb horizontally on the paper and pick the 276×118 size.
Is my thumb impression uploaded?
No. Cleaning and resizing happen in your browser, and the image never leaves your device.
