IBPS RRB thumb impression spec, pre-locked
This page opens the Signature Resizer with the exam and document type locked to IBPS RRB's thumb impression spec: 240x240px at 200 DPI, JPEG format, 20-50 KB.
Why this opens the Signature Resizer
Thumb Impression is an ink-on-paper document, so it shares the Signature Resizer's crop-and-compress engine — this page simply locks the exam and document type to IBPS RRB's thumb impression spec instead of the tool's default.
Source of this spec
Thumb requirement verified (black/blue ink, white paper); size values IBPS-uniform — quoted text confirmed requirement but not the numbers. Sourced from ibps.in — CRP RRBs XIV (2025-26); numeric values IBPS-uniform inheritance — a prior-cycle document (CRP RRBs XIV 2025-26). Re-verify against the current IBPS RRB notification before submitting; this preset updates when the new cycle publishes.
IBPS RRB Thumb Impression — 240x240px, 20-50 KB
This tool locks the Signature Resizer to the IBPS RRB thumb impression spec: 240x240px at 200 DPI, JPEG format, 20-50 KB. Thumb requirement verified (black/blue ink, white paper); size values IBPS-uniform — quoted text confirmed requirement but not the numbers.
One Engine, Every Ink Document
Signatures, thumb impressions, handwritten declarations and finger impressions are all scanned ink-on-white-paper documents, so they share one crop/compress engine on this site. This page is that same engine, pre-locked to IBPS RRB's thumb impression numbers.
Getting a Clean Result First Try
Rejections usually trace to the wrong KB range, wrong pixel dimensions, or a non-JPG format. Because this page pre-locks all three to the verified IBPS RRB numbers, a clear scan on plain white paper is usually enough to clear the portal's validation on the first attempt.
