Where 20KB image limits come from
20KB is the standard ceiling for signatures on SSC, IBPS and most recruitment portals (usually 10KB–20KB). Phone cameras produce 2–5MB photos, so almost every upload needs resizing first.
How it works
The tool re-encodes your image as a JPEG and binary-searches the quality setting until the file is just under 20KB. If it can't fit at the original size, it scales the image down in 20% steps — unless you set exact pixel dimensions, which it always respects.
Tip
Signatures compress brilliantly: crop tightly around the signature first, so the 20KB goes on ink, not on empty paper.
