Completing All Four IBPS & SBI Banking Uploads Without Rejection

Banking recruitment examinations conducted by IBPS (PO, Clerk, SO, RRB), SBI (PO, Junior Associates/Clerk), RBI, NABARD, and LIC require four separate image uploads instead of the usual two:

Passport Photograph: 200 × 230 px (4.5 × 3.5 cm), 20 KB to 50 KB JPG.
Signature: 140 × 60 px, 10 KB to 20 KB JPG (black ink on white paper).
Left Thumb Impression (lti): 240 × 240 px (3 × 3 cm at 200 DPI), 20 KB to 50 KB JPG (blue or black ink on white paper).
Handwritten Declaration (hwd): 800 × 400 px (10 × 5 cm at 200 DPI), 50 KB to 100 KB JPG (black ink on white paper, written by the candidate in English).

Most applicants breeze through the photograph and get stuck on the Handwritten Declaration and Left Thumb Impression for two technical reasons: paper shadows from indoor phone lighting, and the 50 KB / 20 KB minimum byte floor.

Why Declarations Fail the 50 KB Floor (and How This Tool Fixes It)

When you crop a four-line handwritten paragraph to 800 × 400 pixels and whiten the paper background, more than 85% of the canvas is pure white (#FFFFFF). Because the JPEG algorithm encodes 8×8 blocks of solid white in just a few bits, even a high-quality export often lands at 26 KB to 38 KB.

When you upload a 32 KB declaration to the IBPS portal, the validator rejects it immediately because the rule requires 50 KB to 100 KB. Similarly, a clean 240 × 240 px thumbprint often lands at 9 KB to 15 KB and fails the 20 KB to 50 KB rule.

Our tool enforces both walls of the banking specification:

In Declaration Mode (800 × 400 px), it guarantees the exported JPEG lands safely between 55 KB and 96 KB.
In Left Thumb Mode (240 × 240 px), it guarantees the exported JPEG lands safely between 24 KB and 48 KB.

Rules That Cause Disqualification During Scrutiny

Never write the declaration in CAPITAL LETTERS: Just like the signature rule, any declaration written in block capitals or in a language other than English is treated as invalid.
Must be in the candidate's own handwriting: Forensics and handwriting verification compare your uploaded declaration against the passage you write on your admit card in front of the invigilator on exam day.
Do not press the thumb too hard on the stamp pad: A heavy ink blob obscures the friction ridges of your thumbprint, leading to a "thumb impression smudged / not clear" objection. Dab your thumb lightly on the pad, press once on scrap paper, and then make a clean, rolled-free impression on white paper.

How it works

Write the official declaration in English with black ink on white paper (never in ALL CAPS), or press your left thumb on white paper using blue/black stamp-pad ink.
Select the 'Declaration (50–100 KB)' tab for your 800×400 px declaration, or the 'Left Thumb (20–50 KB)' tab for your 240×240 px thumbprint.
Drop the phone photo of your paper into the box above and crop tightly around the writing or thumbprint.
Keep 'Whiten paper background' ticked so room shadows disappear and your ink or thumb ridges stand out clearly on pure white.
Click the resize button to download a JPG guaranteed to sit above the minimum KB floor and below the maximum KB ceiling.

Common questions

What is the exact IBPS and SBI handwritten declaration size in pixels and KB?

All IBPS (PO, Clerk, SO, RRB) and SBI (PO, Clerk) recruitment notifications specify a handwritten declaration of 800 × 400 pixels (10 × 5 cm at 200 DPI) with a file size strictly between 50 KB and 100 KB in JPG/JPEG format, written in black ink on white paper.

What is the exact left thumb impression size for IBPS and SBI exams?

The left thumb impression must be 240 × 240 pixels (3 × 3 cm at 200 DPI) — or 140 × 60 pixels where specified in older regional notices — with a file size between 20 KB and 50 KB in JPG/JPEG format, using blue or black ink on white paper.

Why does my 800x400 handwritten declaration come out at 28 KB (below the 50 KB minimum) on other tools?

Clean black handwriting on pure white paper compresses so efficiently in JPEG that an 800 × 400 image naturally weighs only 25–38 KB—causing the IBPS portal to reject it as 'file size less than 50 KB'. Our tool automatically enforces the 50 KB floor so your file always lands safely between 65 KB and 95 KB.

What is the official IBPS / SBI handwritten declaration text to write?

Write in your own running handwriting in English (not in capital letters): "I, _______ (Name of the candidate), hereby declare that all the information submitted by me in the application form is correct, true and valid. I will present the supporting documents as and when required." You can copy this text with one click at the top of the tool.

What if a candidate does not have a left thumb?

Official IBPS and SBI notifications state that if a candidate does not have a left thumb, they may use their right thumb for applying, and if both thumbs are missing, the impression of the left-hand index finger (followed by middle, ring or little finger) may be uploaded.
