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
WebP
WebP Strengths
- Superior lossy compression — 25–35% smaller than JPEG at equivalent quality
- Supports both animation and full alpha transparency
- Lossless mode available with smaller file sizes than PNG
Limitations
- Slower encoding than JPEG, especially for lossless
- Not supported in Internet Explorer or very old browsers
