Why These Exact Specifications Matter
The signature you upload for SBI Clerk (Junior Associate) is used for verification at the exam center and during document checks, so it needs to display correctly at a small, fixed size. A signature scanned at a different aspect ratio than 140×60 gets squashed or stretched when the portal forces it into that box, which can make it look unrecognizable compared to your usual signature. Preparing it at the correct proportions the first time avoids that mismatch and a possible re-upload.
Common Mistakes to Avoid
- Signing in capital letters: Block-letter signatures are commonly disallowed — sign the way you normally would
- Wrong format: Upload JPEG, not PNG or PDF — most portals reject anything else outright
- File too large or too small: Outside the 10KB–20KB window, the upload is typically rejected
- Wrong dimensions: A signature that isn't roughly 140×60 pixels gets cropped or scaled awkwardly
- Signing with the wrong pen color: Blue ink or pencil often scans poorly — use black ink for the clearest scan
SBI Clerk Signature Specifications — Full Details
This tool targets the signature specification commonly published for SBI Clerk (Junior Associate) recruitment cycles: a 140×60 pixel image, saved as JPEG, sized between 10KB and 20KB, of a signature made in black ink on plain white paper — the same headline numbers used for SBI PO. These figures are corroborated across multiple independent recruitment-guidance sources for the current SBI Clerk cycle, since SBI's own detailed advertisement PDF could not be directly fetched at the time this tool was built. Always verify against SBI's official detailed advertisement PDF for your specific recruitment cycle before final submission. The signature is used throughout the application, admit card, and exam-day verification process.
Frequently Asked Questions
Does resizing reduce signature quality? Minor JPEG compression is applied to meet the 20KB ceiling, but the signature strokes remain clearly legible at the required size.
Does my signature image get uploaded to a server? No. All processing happens in your browser using the Canvas API. Your image never leaves your device.
Is this tool free? Yes. Completely free, no login, no watermark, no limits.
What if my signature still doesn't fit after processing? Sign larger and more centered on the paper before scanning — a signature that fills more of the original frame resizes more cleanly to 140×60 pixels.
Can I reuse the same signature for the photo upload too? No — SBI Clerk requires separate uploads for photograph and signature with different dimensions; use the SBI Clerk photo resizer for your photograph.
Can I use this on mobile? Yes. The tool works on Android and iOS browsers without any app installation.
