The Portable Network Graphics (PNG) format is designed for storing raster graphic data using a lossless compression algorithm known as Deflate. Initially developed as an open and free alternative to GIF, PNG supports three main types of raster images: grayscale, color indexed, and full-color images. PNG files store graphical data in a compressed format, ensuring efficient storage and transmission while preserving image quality without any loss of information.
The High Efficiency Image Container (HEIC) is a file extension adopted by Apple for the HEIF (High Efficiency Image Format) images, typically encoded using the HEVC (High Efficiency Video Compression) codec. This format is particularly suited for Live Photos due to its capability to store image sequences. One of its standout features is its ability to store twice as many pictures as JPEG in the same size and quality, thanks to its next-generation file compression technology. HEIC offers significant advantages for efficient storage and high-quality image representation, making it increasingly popular in modern digital photography and multimedia applications.
