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
PSD

PSD Strengths

  • The undisputed global standard for layered raster graphics and non-destructive image editing
  • Supports incredibly complex compositions combining raster data, vector shapes, live text, and adjustment layers
  • Full support for advanced color spaces (CMYK, Lab, multi-channel) and 32-bit floating-point HDR workflows
Limitations
  • Proprietary format: while the specification is published, complete feature-parity is rarely achieved by third-party software (e.g., smart objects and complex layer styles often break)
  • Files can reach enormous sizes (gigabytes) due to the preservation of unflattened, high-resolution layer data
  • Zero support for native rendering in web browsers or standard mobile image viewers
