About Signature Resizer 10KB to 20KB (140x60 px) Online Free

Resizing a handwritten signature between 10KB and 20KB at tiny dimensions like 140×60 pixels is the #1 cause of form upload errors in Indian government exams. Standard image compressors either blur the ink or shrink the file down to 4KB–6KB, triggering a 'File size less than 10KB' error. SizeSnap combines exact pixel canvas scaling with lossless JPEG byte locking so your signature always lands at a crisp 14KB–16KB.

Compatible with SSC, IBPS, SBI, India Post GDS, Bihar BPSC, UP Police & Delhi Police

Frequently Asked Questions

Why does my 140x60 pixel signature become only 4KB or 6KB in other tools?

Because 140×60 pixels contains only 8,400 total pixels (mostly white paper), standard JPEG encoders compress it to 4–6 KB. SizeSnap solves this by injecting compliant JPEG metadata padding so the file is strictly 15 KB (inside the 10KB–20KB window).

Can I use blue pen for IBPS or SBI signature upload?

No. IBPS and SBI notifications strictly require signatures and handwritten declarations in BLACK ink on white paper.
