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.

WBMP (Wireless Bitmap) is a monochrome (1-bit, black and white) image format defined as part of the Wireless Application Protocol (WAP) specification, developed by the WAP Forum (later consolidated into the Open Mobile Alliance) around 1998. The format was designed for the extremely constrained mobile devices of the late 1990s and early 2000s — phones with small monochrome screens, minimal processing power, and narrow bandwidth GSM data connections. WBMP uses the simplest possible encoding: a type identifier byte (always 0 for the only defined type), width and height encoded as multi-byte integers using a variable-length scheme, and the raw pixel data where each bit represents one pixel (0 for white, 1 for black) packed eight per byte. There is no compression, no metadata, and no color — the format is purely a minimal container for delivering small monochrome graphics to WAP-era mobile browsers. One advantage was extreme efficiency on constrained devices — WBMP images could be decoded with virtually zero CPU overhead and minimal memory, critical on early mobile hardware running at single-digit megahertz clock speeds. The tiny file sizes are another strength: a typical WBMP icon occupied just a few hundred bytes, practical for transfer over 9.6 kbps GSM data channels. While the WAP ecosystem has been entirely superseded by modern mobile web browsers capable of rendering full-color JPEG, PNG, and WebP images, WBMP files remain encountered in archived mobile content from that transitional era.

Frequently Asked Questions

What is the reason to convert XWD to WBMP?

XWD originated in Unix/X11 screenshots and has narrow compatibility today. WBMP offers 1-bit monochrome for mobile devices — a far more practical choice for sharing.

What apps support WBMP?

You can view WBMP with GIMP, IrfanView, ImageMagick, XnView. These tools cover all major desktop and mobile platforms.

How long does XWD to WBMP conversion take?

Most XWD to WBMP conversions complete within a few seconds. The lightweight nature of XWD images means fast processing times.

Is XWD to WBMP conversion free?

You can convert XWD to WBMP for free on Convertio. Premium plans are available if you need higher throughput or larger file allowances.

Does this converter work on mobile devices?

The converter is browser-based and fully responsive. Convert XWD to WBMP from any device — desktop, laptop, tablet, or smartphone.

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.
