About formats

IIQ (Intelligent Image Quality) is the proprietary RAW format developed by Phase One, a Danish manufacturer of medium-format digital camera systems and backs, introduced in 2008 with the P65+ digital back. IIQ files capture the unprocessed readout from Phase One's large-area CCD and CMOS sensors — ranging from 40 to 151 megapixels in current systems — at 16 bits per channel, preserving the full dynamic range, color depth, and spatial resolution of the sensor. The format comes in two variants: IIQ Large (IIQ L), which uses lossless compression for zero-quality-loss archival, and IIQ Small (IIQ S), which applies visually lossless compression to reduce file sizes by approximately 40-60% with negligible quality impact. Phase One's sensor calibration data, including per-pixel defect maps, fixed-pattern noise profiles, and factory color calibration, is embedded in the IIQ file, enabling precise correction during RAW development. One advantage is sheer resolving power and tonal depth: IIQ files from Phase One's flagship systems deliver the highest pixel counts and widest dynamic range available in commercial photography, making them the standard format for museum digitization, fine art reproduction, aerial surveying, and commercial advertising where maximum detail is non-negotiable. Tight integration with Capture One is another key strength — Phase One develops both the camera hardware and the RAW processing software, ensuring that IIQ files receive optimized demosaicing, color rendering, and lens correction tuned to each specific camera-lens combination.

XBM (X BitMap) is a monochrome (1-bit) image format defined as part of the X Window System, originating at MIT around 1987. XBM files are unique among image formats in being valid C source code: each file defines the image as a static array of unsigned char values containing the packed pixel data, preceded by #define statements specifying the image width, height, and optional hot-spot coordinates (for cursor images). The pixel data is stored in hexadecimal byte values within curly braces, with each bit representing one pixel (1 = foreground, 0 = background) and bits ordered LSB-first within each byte. This design was intentional — XBM images could be #included directly into X Window application source code and compiled into the binary, eliminating the need for external file loading and runtime format parsing. The format was used throughout the X11 ecosystem for cursor shapes, window icons, toolbar buttons, and other small UI elements. One advantage is the source-code nature of the format: XBM files can be edited with a text editor, diff'd and merged in version control, generated by shell scripts, and compiled directly into C programs without any image loading library — a level of toolchain integration that no binary image format can match. The format's role as part of the X Window standard ensures it is understood by every X11-aware toolkit and application. While limited to monochrome and no compression, XBM's simplicity makes it an excellent teaching format for understanding bitmap representations. XBM files are supported by all X11 applications, ImageMagick, GIMP, web browsers (as a legacy web format), and programming environments.

Frequently Asked Questions

Why convert IIQ to XBM?

Phase One cameras produce IIQ files with extraordinary resolution. Converting to XBM creates workable deliverables from these massive RAW captures.

What opens XBM?

Text editors (it is plain text), GIMP, and X Window system tools open XBM images.

Does IIQ to XBM conversion work on mobile?

Yes — the converter runs in any modern browser, including mobile devices. No app installation required, just open the page and upload.

Can I batch convert multiple IIQ to XBM?

Upload several IIQ images at once. Each one converts to XBM independently, and you can download them all when finished.

Does converting IIQ to XBM cost anything?

Not for standard use — basic conversions are free. Premium tiers provide faster speeds and additional features for power users.
