What is the difference between lossy and lossless WebP?

Lossless WebP preserves every pixel exactly like PNG but in a smaller file. Lossy WebP applies compression similar to JPEG for even smaller files but with minor quality trade-offs. This tool uses lossless encoding for PNG inputs to preserve image quality.
