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.

Description🔵 The PNM (Portable Any Map) format is a group of image file formats used for portable images, which are maps of pixel values that can represent grayscale or color data. The PNM format family consists of three types of file formats: PBM (Portable BitMap), PGM (Portable GrayMap), and PPM (Portable PixMap).
Technical details🔵 In PBM format, pixel values are binary, with each pixel represented by a single bit. A value of 0 represents black, and a value of 1 represents white. Each row of pixel data is stored as a sequence of bits, padded to the nearest byte.
In PGM format, pixel values are grayscale, with each pixel represented by a single byte. The pixel data is stored as a sequence of bytes, with each row of pixel data stored contiguously.
In PPM format, pixel values are in color, with each pixel represented by three bytes representing the red, green, and blue components. The pixel data is stored as a sequence of triples of bytes, with each row of pixel data stored contiguously.
PNM files can be easily converted between the three formats, as well as to and from other image file formats using various software tools.
