WebMay 26, 2024 · Zooming in a bit, you can see how JPEG XL preserves the text even better than a five-times- larger quality-95 JPEG, which still emits some subtle discrete cosine transform (DCT) noise around the letters. At a similar compression rate, HEIC, WebP, and JPEG look significantly worse than JPEG XL for this image. Original. WebJan 27, 2024 · JPEG decoding is essentially the reverse process. Note that we say that step 4 is lossy because it can’t really be undone. We know what the quantization matrix used to divide the coefficients was, but because the coefficients were rounded, when we multiply we only get an approximation of the original coefficients.
