Description	🔵 Portable Network Graphics, or .png, is a raster graphics file format. Simply put, it's a digital image format. PNG files are popular online because they use lossless data compression and support transparent backgrounds.
Technical details	🔵 Let's look at the technical details of the .png format: PNG compression is lossless, meaning that all the image data is kept during compression. This is different from JPEG, which uses lossy compression and loses some image information to make smaller files. PNG images can range from basic black-and-white (1-bit) to very detailed images with 48 bits of color. They also support 16-bit grayscale images. A key feature of PNG is its support for alpha channel transparency. This lets you create images with varying degrees of transparency, from completely opaque to completely transparent. This is very useful for web graphics. PNG supports a full range of colors (truecolor), allowing for up to 16 million colors. It also supports indexed-color images, which use a palette of up to 256 colors. In short, PNG files are widely used because of their efficient compression, support for many different color palettes, and the ability to handle various transparency levels. These features make them perfect for many web applications.

Description	🔵 The High Efficiency Image Format (HEIF), specifically designed for still images and image sequences, was developed by the Moving Picture Experts Group (MPEG). Its design is based on the High Efficiency Video Coding (HEVC) compression algorithm and uses the .heif or .heic file extensions.
Technical details	🔵 HEIF is an improvement over previous image formats, such as JPEG. It employs more efficient compression algorithms, resulting in smaller file sizes while maintaining image quality. Furthermore, HEIF can support features like transparency, alpha channels, and multiple images (like burst photos or Live Photos on iOS devices) within a single file. Opening HEIF files requires compatible software; popular image viewing and editing software like Apple Photos, Adobe Photoshop, and GIMP are examples. However, older software may not support HEIF natively. In these cases, users need to convert their files to a compatible format before use.
