Thumb Impression Resizer — RBI, SBI, IBPS & NABARD
A thumb impression upload is a small but important part of many banking and government job applications. A file can fail because it is too large, too small, unclear, smudged, or saved in the wrong format. This page gives candidates a simple browser-based way to prepare a clean JPG/JPEG thumb impression.
The common banking preset used here is 240 × 240 pixels, equivalent to 3 cm × 3 cm at 200 DPI, with a 20–50 KB file-size range. RBI Assistant 2026, IBPS RRB recruitment material and recent NABARD recruitment documents explicitly publish this specification.
RBI Assistant Thumb Impression Size
The RBI Assistant 2026 recruitment page requires a left thumb impression on white paper using black or blue ink, JPG/JPEG format, 240 × 240 pixels at 200 DPI, 3 × 3 cm and 20–50 KB. RBI also warns that unclear or smudged uploads may lead to rejection.
IBPS PO, IBPS Clerk & IBPS RRB
IBPS recruitment instructions commonly use 240 × 240 pixels at 200 DPI, 3 × 3 cm and 20–50 KB for the left thumb impression. The IBPS RRB notice also gives alternatives for candidates who do not have a left thumb, with the exact substitution details stated in the notice.
NABARD Grade A
NABARD recruitment documents also specify a left thumb impression on white paper with black or blue ink, JPG/JPEG, 240 × 240 pixels at 200 DPI, 3 × 3 cm and 20–50 KB. The same documents say scanned documents should be clear and use the specified file format and size.
SBI PO and SBI Clerk
SBI recruitment instructions have also used the same banking thumb-impression dimensions and file-size range. Because SBI can change upload rules by recruitment cycle, the active SBI advertisement should be checked before final submission rather than treating one preset as universal.
How to scan a thumb impression for an exam form
Use a clean white sheet and make a fresh impression with the permitted ink. Scan or photograph it in good light, crop closely to the impression, remove large blank margins, and keep the image sharp. Do not use a heavily smudged impression just because it can be compressed to the required KB range.
Why a thumb impression file gets rejected
Common problems include a file above the maximum KB limit, an image below the required quality, the wrong file format, excessive blank space, a blurred impression, or a thumb mark that is too faint to read. This tool checks the final dimensions and file size, but the candidate should still compare the output with the live recruitment portal before uploading.
Frequently Asked Questions
What is the thumb impression size for bank exams?
A common verified banking specification is 240 × 240 pixels in 200 DPI, 3 × 3 cm, JPG/JPEG and 20–50 KB. Check the active notification before submission.
How do I resize a left thumb impression to 240×240 pixels?
Upload your impression, keep Auto dimensions selected, choose the target KB and press Resize & Optimize. The output is generated locally in your browser.
What should I do if my thumb impression is not clear?
Make a fresh impression on clean white paper with good lighting. A fresh sharp impression is usually better than trying to repair a blurry or smudged image.
Why is my thumb impression file size too large?
High image resolution, excess white margins and JPEG quality can increase file size. Crop the image closely and let the optimizer reduce quality while retaining readability.
Can I use a right thumb impression if my left thumb is not available?
Some IBPS instructions provide alternatives when a candidate does not have a left thumb. Follow the exact wording of the active recruitment notice.
Is this thumb impression tool free?
Yes. The page is designed as a free browser-based preparation tool with no server upload required.
