What is it?
XPM (X PixMap) is an image format used by the X Window System, created in 1989 at the Bull Research Center in France by Daniel Dardailler and Colas Nahaboo, and later enhanced by Arnaud Le Hors. It was designed primarily for color icon pixmaps and supports transparent pixels.
An XPM file is plain text, either in the XPM2 form or as a C character-string array that can be included directly in a C program. The data is organized into sections for values (width, height, color count, characters per pixel), a color table mapping character codes to colors, the pixel rows, and optional extensions. Colors can be hex codes or X11 color names, and the keyword None marks transparency.
Technical Specifications
Pros & Cons
Advantages
Unlike XBM, XPM stores color images and supports a transparent color via the None keyword, ideal for icons.
As a C character-string array, an XPM pixmap can be included and compiled directly into an application.
XPM accepts X11 color names as well as hex codes, and can declare color, grayscale and monochrome variants per pixel.
The plain-text structure can be viewed and edited in any text editor, which is handy for small icons.
Disadvantages
Storing pixels as ASCII character codes makes XPM bulky and unsuitable for photographs or large graphics.
XPM is primarily an X Window System icon format and is uncommon outside that and developer contexts.
While some editors support it, XPM has narrower support than mainstream formats like PNG.
When to Use It
XPM is mainly used for color icons and small graphics in X Window System software.
Íconos de aplicación y barra de herramientas
XPM was widely used to define color icons for X11 applications and desktop environments.
Pixmaps compilados
Developers embed XPM data directly in C source so icons ship inside the program binary.

X-based window managers and toolkits use XPM for small color UI elements that need transparency.
How to open a XPM file
XPM files, or X PixMap files, are primarily used for storing pixel-based images in a format that is particularly popular in the Unix/Linux environment. Software for handling XPM files can be categorized into professional graphic design tools, free and open-source applications, web-based viewers, and built-in utilities in various operating systems. Professional tools are suited for users needing advanced editing capabilities, while free and open-source options cater to casual users and developers. Browser-based tools provide quick access without installation, and built-in utilities offer basic functionality for quick viewing.
When choosing software for XPM files, several decision factors come into play, including feature fidelity for editing and viewing, the cost model of the software, platform compatibility, and any export needs for different formats. Users should consider whether they need extensive editing features or simple viewing capabilities, as well as whether they prefer a free solution or are willing to invest in a professional-grade application. Additionally, for users who only need to convert XPM files to more widely used formats, using a conversion tool might be a more efficient option.
