Why this opens the Signature Resizer

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 RBI Grade B'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 RBI Grade B numbers, a clear scan on plain white paper is usually enough to clear the portal's validation on the first attempt.
