Description	🔵 .png (Portable Network Graphics) The .png format is a raster graphics file format that supports lossless data compression. PNG files are widely used on the internet due to their efficient compression and support for transparent backgrounds.
Technical details	🔵 Here are some technical details about the .png format: - Lossless Compression: PNG uses lossless compression, preserving all image data during compression. This is unlike formats like JPEG, which are lossy and discard some information for smaller file sizes. - Bit Depth: PNG images can range from 1-bit (black and white) to 48-bit color, and also supports 16-bit grayscale images. - Transparency Support: A key feature of PNG is its support for alpha channel transparency, allowing for varying levels of transparency in the image, from fully opaque to fully transparent. This is particularly useful for web graphics. - Color Palettes: PNG supports truecolor (16 million colors) as well as indexed-color images with a palette of up to 256 colors.
