Why are PNG files large?
PNG uses a lossless compression format that keeps every single pixel intact without discarding data. When converting a high-resolution camera photo (e.g., 4000x3000px) from a compressed JPG to an uncompressed PNG, the file size naturally multiplies. Using a max resolution limit helps keep files lightweight for web use.
