About formats

PCX (PiCture eXchange) is a raster image format created by ZSoft Corporation in 1985 as the native format of their PC Paintbrush application, one of the first painting programs for IBM PC compatibles. The format uses a simple run-length encoding (RLE) compression scheme that works by replacing consecutive identical pixel values with a count-value pair, achieving modest compression on images with large areas of uniform color. A PCX file consists of a 128-byte header (specifying dimensions, color depth, palette information, DPI, and encoding method), the RLE-compressed pixel data organized in scan-line order, and an optional 256-color palette appended after the image data. The format evolved through several versions supporting increasing color depths: 1-bit monochrome, 4-bit (16 colors), 8-bit (256 colors), and 24-bit true color using multiple color planes. PCX became one of the most popular image formats during the DOS era, widely supported by paint programs, word processors, desktop publishers, and early games throughout the late 1980s and early 1990s. One advantage was broad DOS-era software compatibility — PCX served as a practical interchange format when competing programs used proprietary raster formats. The simplicity of RLE decoding is another strength, requiring minimal CPU and memory resources ideal for the hardware of that period. While PNG, JPEG, and other modern formats have replaced PCX in contemporary use, the format remains encountered in legacy archives and retro computing contexts.

JPG is the most common file extension for images compressed with the JPEG standard, published by the Joint Photographic Experts Group as ISO/IEC 10918-1 in September 1992. The three-letter .jpg extension became dominant due to the 8.3 filename limitation of MS-DOS and early Windows, while .jpeg is the full-length variant — both extensions represent identical file contents and compression. JPEG applies lossy compression using the discrete cosine transform (DCT), dividing images into 8x8 pixel blocks, transforming them into frequency coefficients, quantizing to discard visually insignificant data, and entropy-coding the result. Users control the compression level: higher quality retains more detail at larger file sizes, while lower quality achieves dramatic size reduction with increasing visible artifacts in complex textures. The format supports 24-bit true color (16.7 million colors) and 8-bit grayscale, with Exif metadata embedding camera model, exposure settings, orientation, GPS location, and creation timestamp. One advantage is unmatched device compatibility — JPG is the native output format of virtually every digital camera and smartphone, and is displayed by every image viewer, browser, and operating system in existence. Efficient photographic compression is another strength: real-world photographs with smooth gradients and complex textures compress extremely well under DCT, typically achieving 10:1 reduction at high visual quality. JPG images power the vast majority of photographic content across the web, email, social media, and digital archives worldwide.
