Comparison
JPG vs. PNG: Which Image Format Should You Use?
JPEG utilizes lossy Discrete Cosine Transform compression to achieve small file sizes at the expense of minute high-frequency detail. PNG uses lossless Deflate compression, guaranteeing pristine visual clarity and alpha channel transparency.
