How to Use Signature Resizer & 20KB Compressor
3 Easy Steps- Upload Scanned SignatureUpload a phone camera photo or scanner crop of your signature on white paper.

Uploading a digital signature is a mandatory requirement for almost every competitive examination, recruitment portal, and government identification system in India—including Staff Selection Commission (SSC CGL, CHSL, MTS, GD), UPSC Civil Services, IBPS Bank PO/Clerk, Railway Recruitment Board (RRB), State PSCs, and NSDL PAN Card applications. However, over 40% of registration errors occur due to signature rejection: files exceeding 20KB, dimensions outside 140x60 pixels, or shadowy grey paper backgrounds captured via phone cameras.
**SSC Portal**: 140 x 60 pixels, 10 KB to 20 KB file size, JPG/JPEG format, crisp black or blue ink on clean white background. **UPSC Portal**: 350 x 350 pixels (or 300x120px), 10 KB to 20 KB file size, 200 DPI. **IBPS / SBI Bank PO**: 140 x 60 pixels, 10 KB to 20 KB file size. **NSDL PAN Card**: 200 x 100 pixels, strictly under 20 KB.
When photographing your signature on paper with a smartphone, room lighting often creates dull grey shadows. EtoolMitra's built-in **Auto-Whiten Background Algorithm** separates pen strokes from background paper texture using adaptive luminance thresholding. It turns yellow and grey paper into pure `#FFFFFF` white while simultaneously boosting ink contrast for razor-sharp strokes.
Your handwritten signature is a critical legal identifier. EtoolMitra executes all image resizing, cropping, color thresholding, and kilobyte quantization entirely within your browser using JavaScript and HTML5 Canvas. Your signature is never uploaded, saved, or shared with any external server.
