Modern Format Output

XPM provides color pixmap format for X11 icons — a significant upgrade over the legacy XWD format for everyday image use and sharing.

Batch Processing

Upload multiple XWD files at once and convert them all to XPM in a single session — ideal when you have many legacy images to migrate.

No Install Required

The entire XWD to XPM conversion happens in your browser. No plugins, no desktop apps — just upload, convert, and download.

How to convert XWD to XPM

1

Let the file convert and you can download your xpm file right afterwards

About formats

XWD (X Window Dump) is a screen capture image format defined as part of the X Window System by the MIT X Consortium, dating to approximately 1987. The xwd command-line utility captures the contents of an X window or the entire screen and saves it as an XWD file — functionally equivalent to a screenshot utility but predating the concept by years. XWD files contain a detailed header specifying the X server's visual type, bit depth, byte order, bitmap unit and padding, the window's dimensions, border width, and color map information, followed by the raw pixel data exactly as represented in the X server's framebuffer. This means XWD files faithfully capture the exact pixel representation used by the display hardware — including server-specific byte ordering, padding, and color organization — making them primarily useful on the system where they were captured or on systems with compatible display configurations. The header also stores the window name string and the full color map entries for indexed-color visuals. XWD supports all X11 visual types: StaticGray, GrayScale, StaticColor, PseudoColor, TrueColor, and DirectColor, at any bit depth supported by the X server. One advantage is exact framebuffer fidelity: XWD captures the window's pixel data in its native format without any color space conversion or compression, making it the definitive record of what the X server was actually displaying. The format's integration with the X11 command-line toolkit provides another practical benefit — xwd can capture specific windows by ID or name, be triggered remotely via SSH, and piped directly to format converters. XWD files are handled by ImageMagick, GIMP, xwud (the viewer companion to xwd), and xv.

XPM (X PixMap) is a color image format for the X Window System, developed by Arnaud Le Hors at GROUPE BULL beginning in 1989 as the color successor to the monochrome XBM format. Like XBM, XPM files are valid C source code — each file defines the image as a static array of character strings, where the header strings specify width, height, number of colors, and characters per pixel, the color definition strings map character codes to color values (supporting X11 color names, hexadecimal RGB, and symbolic color types like 'background' and 'foreground'), and the pixel strings encode each row as a sequence of character codes that index the color palette. This ASCII art representation makes XPM images human-readable: one can often see the image content directly in the text of the source file. The format went through three revisions: XPM1 (1989, compatible with X10), XPM2 (simplified syntax), and XPM3 (1991, the current version with the static char* syntax and extended color specification). XPM was the standard format for X Window application icons, splash screens, pixmap buttons, and themed UI elements throughout the 1990s and 2000s. One advantage is the combined benefits of being a valid C source file and a color image: XPM files can be compiled into applications, edited in any text editor, processed by text tools, and version-controlled, while supporting up to 256 colors with transparency (using the 'None' color keyword). The X11 ecosystem's reliance on XPM ensures broad tool support. XPM files are handled by all X11 toolkits, ImageMagick, GIMP, and web browsers (legacy support).
Initial release: 1989

Frequently Asked Questions

Why would I convert XWD to XPM?

XWD is tied to Unix/X11 screenshots. Switching to XPM gives you color pixmap format for X11 icons and broad support across platforms, browsers, and devices.

How do I open a XPM file?

Software that handles XPM includes GIMP, ImageMagick, XnView, Linux image viewers — giving you options on every major operating system.

How long does XWD to XPM conversion take?

Conversion is nearly instant for most XWD files. Since these are small images, the entire process — upload to download — takes only moments.

Can I convert multiple XWD files to XPM at once?

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

Is my XWD file safe when converting online?

Convertio takes privacy seriously — your XWD uploads are deleted after conversion and the XPM results are cleared within 24 hours.

What exactly is the XWD format?

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