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
JPEG is one of the most widely used image formats in computing, standardized by the Joint Photographic Experts Group and published as ISO/IEC 10918-1 in September 1992. The .jpeg extension is functionally identical to .jpg — both contain the same JFIF or Exif-wrapped JPEG compressed image data. The format applies lossy compression using the discrete cosine transform (DCT): images are divided into 8x8 pixel blocks, transformed into frequency coefficients, quantized to discard visually less significant information, and entropy-coded for storage. The quality-to-size tradeoff is user-selectable, with typical settings producing files 10-20 times smaller than uncompressed originals at visually acceptable quality. JPEG supports 8-bit grayscale and 24-bit color, with Exif metadata carrying camera settings, GPS coordinates, timestamps, and thumbnails. One advantage is absolute universality — JPEG is readable by every image viewer, web browser, operating system, camera, phone, and printer manufactured in the past three decades, making it the safest format for sharing photographic images with any recipient. The efficient compression of continuous-tone photographic content is another core strength: JPEG consistently produces compact files from camera sensors and real-world scenes where subtle color gradients dominate. While newer formats like WebP and AVIF achieve better compression ratios, JPEG's installed base is so vast that it remains the default output of digital cameras and the most common image format on the web.

Frequently Asked Questions

What is the reason to convert XWD to JPEG?

XWD is a screen capture format from X Window System with limited modern support. Converting to JPEG (universal lossy format for photographs) makes your images accessible on any modern platform.

Which software can view JPEG files?

JPEG files can be opened with every web browser, image viewer, and photo editor. Most of these are available across Windows, macOS, and Linux.

Is my XWD file safe when converting online?

Your files are secure. Uploaded XWD images are erased immediately after processing, and JPEG outputs are purged within 24 hours.

Can I convert multiple XWD files to JPEG at once?

Absolutely. Batch upload your XWD images and convert them all to JPEG in a single pass — no need to repeat the process for each file.

Is XWD to JPEG conversion free?

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

Does converting XWD to JPEG affect quality?

Quality is maintained to the extent JPEG supports. Since XWD is a screen capture format from X Window System, the visual data transfers cleanly to JPEG.
