About formats

XBM (X BitMap) is a monochrome (1-bit) image format defined as part of the X Window System, originating at MIT around 1987. XBM files are unique among image formats in being valid C source code: each file defines the image as a static array of unsigned char values containing the packed pixel data, preceded by #define statements specifying the image width, height, and optional hot-spot coordinates (for cursor images). The pixel data is stored in hexadecimal byte values within curly braces, with each bit representing one pixel (1 = foreground, 0 = background) and bits ordered LSB-first within each byte. This design was intentional — XBM images could be #included directly into X Window application source code and compiled into the binary, eliminating the need for external file loading and runtime format parsing. The format was used throughout the X11 ecosystem for cursor shapes, window icons, toolbar buttons, and other small UI elements. One advantage is the source-code nature of the format: XBM files can be edited with a text editor, diff'd and merged in version control, generated by shell scripts, and compiled directly into C programs without any image loading library — a level of toolchain integration that no binary image format can match. The format's role as part of the X Window standard ensures it is understood by every X11-aware toolkit and application. While limited to monochrome and no compression, XBM's simplicity makes it an excellent teaching format for understanding bitmap representations. XBM files are supported by all X11 applications, ImageMagick, GIMP, web browsers (as a legacy web format), and programming environments.

Initial release: 1987
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.

Frequently Asked Questions

Why would I convert XBM to RGB?

XBM is a monochrome bitmap from the X Window System with limited modern support. Converting to RGB (Silicon Graphics image format) makes your images accessible on any modern platform.

Which software can view RGB files?

RGB files can be opened with ImageMagick, IrfanView, XnView, GIMP. Most of these are available across Windows, macOS, and Linux.

How long does XBM to RGB conversion take?

Usually just seconds. XBM files are typically small, so the upload, conversion, and download process finishes very quickly on Convertio.

Can I convert multiple XBM files to RGB at once?

Convertio supports batch mode — drag in multiple XBM files and they all convert to RGB together, which is much faster than one-by-one.

Does converting XBM to RGB affect quality?

Your image content stays intact during conversion. Any differences depend on RGB characteristics — such as color depth or compression method.

What exactly is the XBM format?

XBM is a monochrome bitmap from the X Window System. Originally from X11/Unix, it has become a legacy format — conversion is the most practical way to use these images today.
