JPEG vs HEIC Compression

In this video, we break down what HEIC images are, how they work, and why your iPhone saves photos in this format instead of JPG. We explain image compression in simple terms — especially how brightness (luminance) is preserved while color information is compressed. You'll learn how HEIC achieves better quality at smaller file sizes compared to JPEG, and what color subsampling really means. We also show how to convert HEIC files to JPG or PNG using Python, and visualize how compression affects color and luminance channels. Perfect for anyone curious about modern photo formats and image compression! To access the code, use the following link: https://github.com/mortezmaali/HEIC2J...
