Convert X PixMap images (XPM) online for free
The converter easily converts your XPM images to various formats - free and online. No X Window System or or other Raster Image software needed.
The converter also works in reverse, so you can convert other "Text-Based Image Format" formats to XPM without using software like X Window System or a similar tool.
The .XPM (X PixMap) format is an ASCII text-based raster image format originally created for the X Window System. It was designed to store icon images and supports transparent pixels. Uniquely, the image data is formatted as a C language character array, allowing developers to embed the image directly into C and C++ source code without needing external image loaders. Scientific programs, most notably the GROMACS molecular dynamics software suite, also generate .XPM files to display 2D matrices of computational data.
The biggest disadvantage of the .XPM format is its extreme inefficiency. Storing pixel data as plain ASCII text rather than binary data results in heavily bloated file sizes. Furthermore, modern web browsers, default mobile photo galleries, and standard OS image viewers (like Windows Photos or Apple Preview) do not support .XPM files natively, making them difficult to share or view outside of specialized Linux/Unix environments.
To use these images practically today, you must convert them. For web use, archiving, and sharing, convert .XPM to PNG or WEBP to drastically reduce file size while perfectly retaining transparency. For basic printing or embedding in documents, JPG is ideal. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
Note that a small percentage of .XPM files function as XML-based MPC Program Files used by Akai Professional music production software or spectroscopy parameter files for Bruker equipment. Drop your file here, and convert.guru will analyze its internal signature to accurately process it.
Use Convert.Guru to open and convert your XPM file.
Users also converted XMP, LUT, CUBE, PNG, JPG, XBM, CIT, JPF, DNG and SVG files.
If you want to convert XPM file to DNG or CUBE, you can use X Window System or similar software from the "Raster Image Storage" category. In the File menu, look for Save As… or Export….
To convert files to XPM, try X Window System or another comparable tool in the "Raster Image Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our XPM converter.
