IBPS PO & Clerk 2026: Complete Photo, Black-Ink Signature & Thumb Impression Guide
Need to fix your photo or signature right now?
Applying for banking examinations conducted by IBPS (PO, Clerk, SO, RRB), SBI (PO, Junior Associates), RBI, and LIC is uniquely challenging because candidates must upload four separate image files—each governed by different pixel dimensions, file size brackets, and strict ink-color rules. Instead of using separate tools, use the IBPS 4-in-1 Photo, Signature, Thumb & Declaration Resizer to calibrate every file in your browser.
1. The Master IBPS & SBI 4-Document Specification Table (2026)

2. Critical Disqualification Traps in Banking Forms
Trap #1: Mixing Up Ink Colors Between Signature and Thumb
In IBPS and SBI exams, blue ink is strictly prohibited for signatures and handwritten declarations. Both must be written with a black ballpoint or gel pen on clean white unruled paper. Conversely, your Left Thumb Impression (LTI) can be made with either a blue or black ink pad. Do not press your thumb too hard on the paper; excessive ink fills in the friction ridges and causes biometric software to flag the image as a solid blotch.
Trap #2: Blurry Handwritten Declarations at 800×400 Pixels
The handwritten declaration contains roughly 35 words across 3 to 4 lines. If you compress it using a generic 20KB tool, the words become illegible. Because IBPS allows a generous 50KB to 100KB window at 800 × 400 pixels, use our Compress Image to 100KB or Resize Image in Pixels tool set to 800×400 px and 75KB so every single letter remains crisp.

Frequently Asked Questions
Why does IBPS reject signatures signed in blue ink?
IBPS and SBI official notifications explicitly state that the candidate’s signature must be signed on white paper with a BLACK ink pen only. Signatures in blue ink—or in capital letters—are rejected during biometric/document verification.
What is the exact text for the IBPS Handwritten Declaration in 2026?
The standard declaration text is: "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." It must be written in your own handwriting in English with black ink.
Can I use black ink for the Left Thumb Impression in IBPS exams?
No. While the signature and handwritten declaration must be in black ink, the Left Thumb Impression must be stamped using a blue or black stamp pad on white paper, clearly showing ridge lines without smudging.
