IBPS photo, signature, thumb impression and handwritten declaration: all four in one place

By CompressInKB8 min read910 words

Some IBPS recruitment forms ask for a photograph, signature, left thumb impression and handwritten declaration. Requirements differ by post and cycle, so check your current notice and application before preparing any files.

This guide describes useful checks and examples. These figures are not a universal specification; follow the official IBPS notice for the particular application.

Exam rules change. Verify every file requirement with your current official notification. If the portal requires live-photo capture, a resized image cannot replace it.

The four uploads

The following are example starting values, not universal requirements. One IBPS-hosted 2026 guideline lists 200 ร— 230 and 20โ€“50 KB as preferred for a photo and 140 ร— 60 and 10โ€“20 KB as preferred for a signature. Check all four requirements against your own recruitment notice; SBI and RBI issue their own instructions.

The re-encoding trap

Application systems can reject files for several reasons, including the wrong format, dimensions or file size. We cannot inspect how a particular portal handles each upload, so do not assume a re-encode is responsible without an error explaining it.

If your notice specifies a size range, aim comfortably within it and keep the image legible. A margin is useful but cannot guarantee a portal will accept a file.

Keep the unmodified original and inspect the exported file. Follow the portal error, if any, instead of repeatedly compressing a file until it becomes unreadable.

Photograph: 200 ร— 230 is small

At 200 ร— 230 pixels you have 46,000 pixels to work with, which is enough for identification and not much else. Crop tightly: face filling about three-quarters of the height, light background, no shadow on the face, both eyes open and visible. Because the canvas is tiny, any distortion introduced by squeezing a wide photograph into this ratio is magnified โ€” crop to 200:230 first, then scale.

Avoid upscaling. If your source photograph is smaller than 200 ร— 230 you will be inventing pixels, and soft invented detail is exactly what a verification officer notices. Retake instead.

Left thumb impression: getting it clean

Press the left thumb flat on a plain white sheet using a stamp pad, in the centre of the page, well away from the edges and from any previous attempt. The impression should be whole โ€” the whorls, loops and ridges all in frame โ€” and dark enough to show ridge detail without being a solid black smudge. Over-inking destroys the very detail the impression exists to provide.

Photograph or scan the sheet flat, straight-on, in even light with no shadow falling across the print, then crop to 240 ร— 240 and compress into 20โ€“50 KB. If your impression turns out smudged, do not clean it up with an editor โ€” take a new impression. Retouching a biometric identifier is not something you want in an application file.

Handwritten declaration: the one people get wrong

The declaration is a specific paragraph in a specific language that you write out by hand, in the format the notification prescribes, and upload as an 800 ร— 400 pixel image. The two failure modes are writing at an angle so that the text runs off the crop, and writing in the wrong language or script for the post applied for.

Use clean paper and write the exact wording in the language and ink specified by the current notice. Leave a clear margin, photograph the page straight-on in even light and check that every word remains visible. Resize and compress only to the dimensions and byte range the notice permits; do not assume an export quality will produce a particular file size.

If the notification specifies a language other than your first language, write it in that script by hand rather than typing and printing it. The requirement is a handwritten declaration, and a printed one is a rejection at verification even when the upload succeeds.

Build a folder, not a last-minute scramble

Create a private folder for the recruitment and keep the exact files you uploaded alongside the originals. Check the instructions for later stages rather than assuming the same files will be required again. Protect these identity documents and do not post them publicly.

Frequently asked questions

Are the IBPS upload sizes the same for PO, Clerk and Specialist Officer?

The four uploads and their dimensions have been consistent across IBPS recruitments in recent cycles, but each notification is published with its own specification section. Read that section before uploading โ€” this guide is a record, not the authority.

My thumb impression has a ridge pattern that is hard to scan. What should I do?

Use fresh ink and moderate pressure on plain white paper, photograph it under even, diffuse light from directly above, and crop tightly to the impression. If the ridge detail is not visible in the source image, no compression setting can recover it โ€” take another impression.

Do I need the declaration in Hindi or English?

The notification states the language, often English, sometimes Hindi, and sometimes either. Write it by hand in the prescribed language; the guideline is about verifying that you wrote it yourself, so a printed or typed version will not do.

Why was my file rejected when it is 48 KB and the limit is 50 KB?

The cause is not necessarily re-encoding. Check the exact error, actual format, dimensions, byte size, file field, session and current official instructions. If needed, ask the official help channel.
