IBPS Bank thumb impression size

What size does the IBPS Bank thumb impression need to be

The IBPS Bank form wants the thumb impression at 240 by 240 pixels, saved as a JPG, with the file somewhere between 20 and 50 KB. At 300 DPI that works out to roughly 2.0 by 2.0 cm on paper. All three conditions have to hold at once. Getting the pixels right will not help if the file is the wrong weight, and a file of the right weight fails if the dimensions are off. The portal checks each one separately and the error message it shows rarely tells you which one failed.

What the shape means for cropping

240 by 240 pixels is a ratio of 1:1, which is close to square. The target is close to square. A portrait photo loses a little from each side, which is usually fine for a head and shoulders shot. Open More controls above if you want to switch between cropping the edges to fill the frame and keeping the whole image with white space around it.

Why the range is 20 to 50 KB

People tend to read only the upper limit and compress the file as small as it will go. That is the single most common mistake. A file under 20 KB is rejected exactly as firmly as one over 50 KB, because the portal tests both ends. This tool searches for the best quality that still fits under 50 KB, and if the result lands below 20 KB it lifts the file back into range without altering a single pixel. The ceiling is generous for an image this small. Files here tend to come out under the minimum rather than over the maximum, and the tool lifts them back into range when that happens.

How to do it

Tap the box above and pick your image. The preset is already set to IBPS Bank thumb impression, so the width, height and KB range are filled in and you do not need to type anything. Press Resize. The result appears below with a three line checklist covering pixel size, file size and format. Green against all three means the portal will accept it. Then press Download JPG and upload that file to the form.

Doing it on a phone

Hold the phone straight above the paper and get close enough that the impression fills a good part of the frame, but not so close that the camera cannot focus. Tap the screen on the print to lock focus before you shoot, because an out of focus thumb impression loses the ridge detail that makes it usable.

What your original needs to be

The target here has a long edge of 240 pixels. Anything from a phone camera in the last decade is far bigger than that, so you have room to spare. Aim for an original with a long edge of at least 480 pixels and the result stays sharp. What you must avoid is feeding in something already smaller than 240 by 240, because scaling an image up cannot invent detail that was never captured. That is why a crop from a group photo, or a screenshot, tends to look soft no matter what you do to it afterwards.

Which exams this covers

These dimensions apply across Thumb impression. The bodies running them keep the thumb impression specification consistent between its papers, so one correctly sized file usually serves every form you fill under it that season. Save the 240 by 240 version you download here and you can reuse it, but check each notification anyway, because a single paper occasionally departs from the standard.

Taking the thumb impression

Use a blue or black stamp pad rather than ink from a ballpoint pen. Press your thumb straight down onto plain white paper and do not roll it, or the ridges will smudge. Press gently. Too much pressure spreads the ink and the ridge pattern disappears entirely. Let it dry fully before you photograph it.

Which thumb

Most forms ask for the left thumb. Confirm this in your notification, because the wrong thumb can cause problems at document verification. The impression needs to be clear. A smudged or partial print will not be accepted.

If the upload is still rejected

Read your notification again and check the numbers against this page. Exam bodies revise them between cycles, and the 240 by 240 px and 20 to 50 KB shown here reflect a previous notification. If your notice says something different, type those numbers straight into the width, height and KB boxes above, which are all editable. If it still fails after that, try a different browser, and try renaming the file. Some portals quietly reject file names containing spaces or special characters.
