Under 10 KB cap
Ink lines legible on white paper
By downsampling unnecessary background noise, sharpening black ink edges, and applying high-efficiency JPEG quantization, the tool compresses file size down to 5–9.9 KB while preserving fine stroke details.
Strict recruitment portals like IBPS, SBI Clerk/PO, SSC GD, and several state public service commissions strictly enforce a 10 KB upper limit for signature uploads.
