GIF

GIF Strengths

  • Universal support across all web browsers, operating systems, and messaging apps
  • Supports basic frame-by-frame animation out of the box
  • Lossless compression is highly effective for simple, flat-color graphics like logos or pixel art
Limitations
  • Limited to 256 colors per frame, resulting in poor quality for complex gradients and photographs
  • Animations produce massive file sizes compared to modern formats like MP4, WebP, or AVIF
  • 1-bit transparency limits edge blending on non-uniform backgrounds
TIFF

TIFF Strengths

  • Universally accepted as the gold standard for high-fidelity archival and professional print workflows
  • Highly adaptable structure supports multiple pages (documents), layers, vast bit depths, and diverse compression algorithms within a single file
  • Unmatched support for rich metadata including EXIF, IPTC, XMP, and custom ICC color profiles
Limitations
  • Produces exceptionally large file sizes compared to modern web formats
  • The 'x-tiff' legacy MIME string forces developers to write extra validation logic to prevent strict security filters from rejecting valid uploads
  • The format's immense complexity means that many lightweight parsers only implement a subset of the specification, sometimes failing to read obscure compressions (like CCITT or old JPEG-in-TIFF)

When to choose which format
