BTIF Strengths

  • Allowed early digital archiving and web-based transmission of cleared bank checks
  • Encapsulated both image data and ASCII transaction metadata in a single file
Limitations
  • Completely proprietary and obsolete format
  • Lacks native support in modern operating systems and image viewers
  • Requires legacy plugins or specialized bio-format readers (like ImageC) to decode
JPEG

JPEG Strengths

  • Universal support — every browser, OS, and application handles JPEG
  • Excellent compression for complex photographs with natural color gradients
  • Rich metadata support: EXIF (GPS, camera settings), ICC color profiles
Limitations
  • No transparency — cannot have a transparent background
  • Lossy compression introduces visible artifacts on sharp edges and text
  • No animation support
