Complete Guide: UPSC Online Application Signature Guidelines & Resizing
The Union Public Service Commission (UPSC) conducts India's most prestigious national examinations, including the Civil Services Examination (CSE), NDA & NA, CDS, Engineering Services (ESE), and CAPF through its One Time Registration (OTR) and online application portal (upsconline.nic.in).
Unlike other recruitment bodies that demand tiny 10KB to 20KB files, UPSC enforces higher resolution parameters to ensure crystal-clear digital verification at examination centers and interview personality tests:
- Minimum Dimensions: 350 pixels (width) × 350 pixels (height)
- Maximum Dimensions: 1,000 pixels × 1,000 pixels
- File Size Range: 20 KB to 300 KB
- Format: JPG / JPEG format only
UtilityHub's UPSC Signature Resizer comes pre-set with these exact dimensional and byte requirements. Upload your scanned signature, ensure optimal sharpness, and download a compliant image in seconds.
How to Prepare a UPSC-Compliant Signature
- Sign on Plain White Paper: Use a high-quality black ink pen (strictly recommended by UPSC guidelines for maximum optical contrast) on unruled, clean white paper. Avoid gel pens that bleed or faint ballpoint pens.
- Capture or Scan: Take a flat, well-lit photo from your smartphone or use a flatbed scanner at 200–300 DPI. Avoid cast shadows.
- Upload to UtilityHub: Drag and drop your image into the tool above.
- Verify UPSC Preset: Select the “UPSC Signature (Min 350x350 px)” preset. The pixel size is pre-calibrated to 350×350 and target size to 250 KB.
- Download & Upload: Download your finished file and submit it to the UPSC OTR portal without any technical glitches.
