How Image Compression Works
Image compression is the process of reducing the file size of an image while preserving as much visual quality as possible. There are two main types of image compression:
- Lossy Compression: This method removes some image data to achieve higher compression rates. It is commonly used for JPG and WebP formats. Lossy compression can significantly reduce file size, but may introduce slight visual artifacts or quality loss, especially at lower quality settings. It is ideal for photographs and web images where small file size is more important than perfect fidelity.
- Lossless Compression: This method reduces file size without losing any image data or quality. PNG and GIF formats typically use lossless compression. The resulting files are larger than lossy-compressed images, but the visual quality is perfectly preserved. Lossless compression is best for graphics, icons, and images requiring transparency or sharp edges.
Choosing the right compression type depends on your use case: use lossy for smaller files and faster loading, or lossless for perfect quality and transparency.
Supported Formats
- JPG/JPEG
Best for photographs and complex images with many colors. Uses lossy compression to achieve smaller file sizes.
- PNG
Ideal for images requiring transparency or sharp edges. Supports lossless compression for perfect quality.
- WebP
Modern format offering superior compression for both lossy and lossless images. Provides better quality at smaller file sizes compared to JPG and PNG.
