Compress Signature Between 10KB and 20KB
Most Indian government exams (SSC CGL, IBPS PO, RRB NTPC) require signatures "between 10KB and 20KB." Too small and the portal says "file too small." Too large and it says "file exceeds limit." This tool targets the exact 10KB-20KB sweet spot so your upload is accepted on the first try.

How it works
Crop tightly around the signature
Remove all blank paper margins. A tightly cropped image compresses much more predictably into the 10KB-20KB range.
Set target to 18KB
We target 18KB by default - safely above the 10KB minimum and comfortably below the 20KB maximum.
Verify and upload
Check the final file size, then upload directly to your exam portal. It will be accepted immediately.
Frequently asked questions
Why 18KB and not exactly 20KB?
Some portals calculate file size slightly differently than your browser. Targeting 18KB gives you a safe buffer so you never accidentally exceed the 20KB limit.
What if my compressed signature is under 10KB?
If your signature is very simple (few strokes), it may naturally compress below 10KB. In this case, try using a slightly larger crop area or slightly higher quality setting to bring it above 10KB.
Which exams use the 10KB-20KB range?
SSC CGL, SSC CHSL, IBPS PO, IBPS Clerk, RRB NTPC, RRB Group D, and many state PSC exams use this exact 10KB-20KB range for signature uploads.
