📥 PNG vs JPG: Which Format to Choose?

RECOMMENDED

PNG Format

  • ✅ Transparent background - No white box around signature
  • ✅ Looks professional on any colored document/PDF
  • ✅ Perfect for overlaying on forms
  • ✅ No quality loss (lossless compression)
  • ✅ Best for official documents

Use when: Uploading to PDF forms, colored backgrounds, professional documents

JPG Format

  • ⚠️ White background only - Adds white box around signature
  • ✅ Smaller file size (good for 10-20KB requirements)
  • ⚠️ Less versatile - only works on white backgrounds
  • ✅ Supported by all exam portals

Use when: Exam portals specifically require JPG, file size must be under 20KB

Our Recommendation: Always download PNG first. If exam requires JPG or smaller file size, use our Image Compressor to convert to JPG and reduce size.

📏 Signature Size Requirements by Exam

Exam Dimensions (cm) Dimensions (pixels) File Size
SSC 4.0 x 2.0 cm 520 x 260 px 10-20 KB

Banking 4.0 x 2.0 cm 520 x 260 px 10-20 KB
Railways 3.5 x 1.5 cm 420 x 180 px 10-20 KB
