About formats

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.

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.

Frequently Asked Questions

Why convert FAX to XWD?

FAX files require specialized fax viewers. Converting to XWD lets anyone open the content easily.

What software opens XWD?

Use xwud command, GIMP, or X Window System tools to view XWD files.

Is any detail lost during conversion?

FAX files are typically monochrome scans. The converter maintains full resolution and sharpness in XWD output.

Does the FAX to XWD converter cost anything?

The converter is free for standard use. Premium plans offer expanded limits and priority queue access.

Can I batch convert FAX to XWD?

Upload multiple FAX files together — the converter processes each one and delivers separate XWD outputs.

Is my data secure during conversion?

Uploaded FAX files are deleted immediately after conversion. XWD results are automatically removed within 24 hours.
