Description	🔵 .jpeg (Joint Photographic Experts Group) The .jpeg format, also known as JPG, is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing for a selectable tradeoff between storage size and image quality. JPEG is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the World Wide Web.
Technical details	🔵 The JPEG (.jpeg or .jpg) format, created by the Joint Photographic Experts Group, is widely used for digital photography and online images. It employs lossy compression, reducing file size by omitting some image data, allowing a balance between size and quality. JPEG usually uses the YCbCr color model (8 bits per channel) and supports sRGB color space, RGB, and CMYK models. Compression levels are adjustable, affecting both size and quality: higher compression decreases size and quality, while lower compression increases both. JPEG images can be scaled down with minimal quality loss but scaling up can degrade quality. The format supports extensive metadata and offers progressive JPEGs for gradual loading on slow connections. Widely compatible, JPEG is ideal for photographs but less so for sharp contrast images like line drawings or text. Each re-save degrades quality slightly due to its lossy nature. Understanding this format is essential for those involved in photography, graphic design, web development, or any digital image-related field.

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.
