Understanding Image Compression Types

Lossless Compression

Reduces file size without losing any image data or quality. Perfect for technical images, screenshots, and graphics where every detail must be preserved. Typically achieves 10-50% size reduction.

Lossy Compression

Significantly reduces file size by removing some image data that’s less noticeable to human vision. Ideal for photographs and complex images where small quality trade-offs are acceptable for major size savings. Can achieve 50-90% reduction.

Adaptive Compression

Our smart compression that automatically chooses the best approach for each image, balancing quality and file size based on image content, format, and intended use case.

Common Use Cases for Image Compression
