Which thumb should I use?

Most forms ask for the left thumb. Follow your own form: IBPS, for example, allows the right thumb if the left is missing. The tool only cleans the photo; it does not change which thumb it is.

What size is a thumb impression for IBPS?

The IBPS notification asks for a JPG of 240 x 240 pixels at 200 DPI between 20 KB and 50 KB, with black or blue ink on white paper. Pick the IBPS preset and the file is made to that size.

Why is my file bigger than the image needs?

A small, clean thumbprint compresses to a few KB, but forms like IBPS reject files under 20 KB. The tool adds harmless padding inside the JPG so it meets the minimum without changing the picture.

Can this tool create a thumbprint for me?

No. It only cleans up a photo of a real impression you made with ink. It never draws, generates or alters ridge detail.

Is my photo uploaded?

No. The photo is processed in your browser and never leaves your device.

Can this make my thumb impression?

A photo of my inked thumb on paper

The paper and shadows are removed and only the ink is kept.

The form needs N x N pixels within a KB range

Use a preset or enter the size; the JPG is made to fit, padded up to any minimum.

A biometric fingerprint scan

Biometric capture needs a fingerprint scanner at a centre. This tool only prepares an ink impression photo.

Creating an impression without inking my thumb

The tool never generates prints. Make a real impression with a stamp pad first.

How to get a clean thumb impression

Taking the photo

Use a stamp pad with blue or black ink and press your thumb firmly, rolling slightly so the whole pad prints.
Print on plain white paper. Let it dry for a minute so it does not smudge.
Photograph straight from above in daylight or under a bright light. Avoid your phone casting a shadow over the print.
Fill a good part of the photo with the print, but keep some white paper around it.

If the result looks wrong

Ridges broken or patchy: move Sensitivity towards "Fainter ink", or take a new print with more ink.
Grey smudges around the print: move Sensitivity towards "Dark ink only".
Nothing detected: the print may be too faint or the photo too dark. Retake it in better light.

Matching the form

Upload forms check the pixel size and file size. The IBPS preset follows the left thumb impression rules in the official IBPS notification (JPG, 240 x 240 px at 200 DPI, 20-50 KB). For any other form, choose "Custom size" and enter the numbers from its instructions.
