Answer from AI
- Raster (Bitmap):
- JPEG (.jpg, .jpeg): Good for photographs, supports lossy compression. Does not support transparency.
- PNG (.png): Supports transparency (alpha channel). PNG-8 for simple images with a palette, PNG-24 for higher quality with full color range. Lossless compression.
- GIF (.gif): Supports animation and transparency. Limited to 256 colors. Used for simple animations and icons.
- WebP (.webp): Developed by Google. Supports lossy and lossless compression, animation, and transparency. Usually smaller in size at similar quality compared to JPEG and PNG.
- Vector (Vector graphics):
- SVG (.svg): Scales without loss of quality. Great for logos, icons, and charts. Based on XML.
| Format | Type | Transparency | Animation | Compression | Best use case |
|---|---|---|---|---|---|
| JPEG | Raster | No | No | Lossy | Photographs |
| PNG | Raster | Yes | No | Lossless | Images with transparency, graphics |
| GIF | Raster | Yes (simple) | Yes | Lossless | Simple animations, icons |
| WebP | Raster | Yes | Yes | Lossy/Lossless | Universal |
| SVG | Vector | Yes | Yes (CSS/JS) | Lossless | Logos, icons, graphics |
The choice of format depends on the type of image, quality requirements, support for transparency and animation, as well as the necessary file size. Using <picture> or the srcset attribute in the <img> tag allows offering different formats (e.g., WebP and JPEG) depending on browser support for performance optimization.
