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.
Developer: MIT X Consortium
Initial release: 1987
RGBO is a raw pixel data format designation used by ImageMagick, the open-source image processing suite first released in 1990, representing images as a flat sequence of Red, Green, Blue, and Opacity (inverted alpha) sample values with no header, container, or compression. The RGBO channel ordering specifies that the fourth channel is opacity rather than alpha — where alpha represents transparency (0 = transparent, max = opaque), opacity represents the inverse (0 = opaque, max = transparent). This distinction matters in compositing pipelines where the mathematical convention for the fourth channel varies between systems: some compositing models work with alpha (transparency), while older conventions including portions of ImageMagick's internal processing historically used opacity. RGBO files contain raw sample data at a user-specified bit depth (8-bit, 16-bit, or floating-point per channel), with pixels stored in scanline order. Because there is no header, the image dimensions, bit depth, and endianness must be specified externally when reading the file — typically via ImageMagick command-line arguments. One advantage is direct compatibility with processing pipelines that use the opacity convention: RGBO eliminates the need for channel inversion when interfacing with systems that expect opacity rather than alpha, preventing subtle compositing errors that occur when transparency conventions are mixed. The format's raw-data nature provides another practical benefit — with no encoding overhead, RGBO data can be memory-mapped, processed with SIMD instructions, or piped between processes with minimal latency. RGBO is primarily used within ImageMagick processing chains and can be converted to any other format using ImageMagick's extensive format support.

Frequently Asked Questions

Why would I convert XWD to RGBO?

XWD is a screen capture format from X Window System with limited modern support. Converting to RGBO (SGI format variant with opacity data) makes your images accessible on any modern platform.

Which software can view RGBO files?

RGBO files can be opened with ImageMagick, specialized graphics tools. Most of these are available across Windows, macOS, and Linux.

Are my uploaded files kept private?

Your privacy is protected. All uploaded files are erased after conversion and output files are purged within 24 hours — nothing is stored long-term.

Is XWD to RGBO conversion free?

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

Can I convert multiple XWD files to RGBO at once?

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

How long does XWD to RGBO conversion take?

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