About formats

RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.
Initial release: 1990
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.

Frequently Asked Questions

Why convert RGB to PCX?

Since RGB has no file structure, most viewers reject it. PCX conversion adds the necessary format structure for universal compatibility.

What programs open PCX files?

PCX files can be opened in IrfanView, XnView, GIMP, Photoshop, and many legacy graphics applications.

Can I convert RGB to PCX on my phone?

Yes — the converter works in mobile browsers on both Android and iOS. No app installation needed, just open the page and upload.

Is my RGB data safe during conversion?

Yes — uploaded data is processed securely and deleted immediately after conversion. Output files are removed from servers within 24 hours.

What makes PCX a good target format?

PCX offers legacy DOS format, RLE compression, indexed color. It gives your raw RGB data a proper structure that any image viewer or editor can handle.
