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
SVG

SVG Strengths

  • Provides infinite resolution scalability, looking perfectly crisp on high-DPI (Retina) displays without increasing file size
  • Extremely lightweight compared to raster formats for flat graphics, logos, and UI elements
  • Can be manipulated dynamically via the browser's CSS and JavaScript engines (DOM integration)
Limitations
  • Unsuitable for complex photographic images or photorealistic textures
  • Poses critical security vulnerabilities (XSS and XML External Entity attacks) if user-uploaded SVGs are not heavily sanitized
  • Rendering performance degrades significantly if the SVG contains tens of thousands of complex nodes or deeply nested paths

When to choose which format
