Guidelines for Signature Upload in Sarkari Application Forms
Uploading a blurry or improperly formatted signature is one of the leading causes of form cancellation in government examinations like Banking (IBPS PO, Clerk, SBI), SSC (CGL, CHSL), and Central Police Organizations. When scanning an inked signature on paper, modern smartphone cameras capture images at 3 to 10 Megabytes, which servers immediately reject.
Standard Official Signature Requirements:
- Ink & Paper: Candidates must sign with a black or dark blue ink pen on clean white unruled paper. Signatures done with pencil or in capital block letters are strictly prohibited.
- Permissible File Size: The resulting JPEG image file size must fall strictly between 10 KB and 20 KB.
- Aspect Ratio & Dimensions: Standard dimension criteria are 4.0 cm width by 2.0 cm height (approximately 140 pixels wide by 60 pixels high).
Why Use This Signature Compression Tool?
When compressing small black-on-white images, regular resizers often degrade contrast, causing the signature strokes to disappear into a washed-out grey haze. This tool applies intelligent threshold preservation to keep strokes dark, crisp, and fully legible while shaving away unneeded metadata to hit the precise 10KB to 20KB requirement.
Instructions to Get 100% Form Acceptance:
1. Sign on blank white paper and take a well-lit photo.
2. Crop the whitespace tightly around the signature.
3. Upload it above and click "Compress Signature". The tool generates an optimized JPEG ready for instant upload.
