Choosing the right format can be the difference between a sluggish website and an ultra-fast one.
1. JPG (JPEG)
- **Best For**: Real-world photographs, complex gradients, backgrounds.
- **Pros**: Universally supported across every device on Earth.
- **Cons**: No alpha transparency support.
2. PNG
- **Best For**: Logos, icons, screenshots, graphics with sharp text and transparent layers.
- **Pros**: True lossless compression and full 8-bit alpha transparency.
- **Cons**: Can be very heavy for large photos.
3. WebP
- **Best For**: Modern web applications and blogs.
- **Pros**: Combines JPEG-like lossy compression with PNG-like transparency, typically 30% smaller than both.
- **Cons**: Older legacy photo viewers (pre-2020) may require conversion.
Recommendation
Use WebP for your production web applications. When creating transparent logos or vector exports, use PNG. When sharing universal photos, use JPG!
