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.

VIPS is the native file format of the libvips) image processing library, originally developed by John Cupitt and Kirk Martinez at the National Gallery in London during the VASARI project (1989-1993) for high-resolution digitization and analysis of paintings. The VIPS format stores large images in a simple, memory-mappable layout: a header containing image dimensions, number of bands (channels), data type (8/16/32-bit integer, float, double, complex), color interpretation, resolution, and offset metadata, followed by the raw pixel data in band-interleaved format. This straightforward layout allows the operating system's virtual memory manager to map the file directly into address space, enabling libvips to process images much larger than available RAM by paging portions in and out as needed — a technique called demand-driven evaluation. VIPS files support images with any number of bands at any of the supported numeric types, accommodating everything from standard RGB photographs to hyperspectral datasets with hundreds of bands. One advantage is large-image performance: libvips's architecture processes images in small tiles evaluated on demand, meaning a 100,000 x 100,000 pixel image can be cropped, resized, sharpened, and saved without loading the entire image into memory — a capability that makes VIPS the engine behind image processing services handling millions of web images. The format's scientific heritage is another strength — the VASARI project required analyzing paintings at ultra-high resolution with multispectral imaging, and the VIPS format's support for arbitrary band counts and floating-point precision reflects these computational imaging origins. VIPS files are primarily used with the libvips library (available for C, Python, Ruby, and other languages) and can be converted to other formats via vips command-line tools or ImageMagick.

Frequently Asked Questions

Why convert IIQ to VIPS?

IIQ files from Phase One medium format cameras can reach 150MP and need conversion to practical formats like VIPS for client delivery and sharing.

What opens VIPS?

The libvips library, nip2 GUI, and applications built on libvips open VIPS format images.

Will the image quality be preserved?

The converter extracts full quality from IIQ RAW data and renders it into VIPS with the best possible fidelity for the target format.

Can I convert IIQ to VIPS on my phone?

Absolutely. The converter works in any mobile browser — iOS Safari, Android Chrome, or any other. No app installation necessary.

Is IIQ to VIPS conversion free?

Standard conversions are available at no cost. Premium plans add faster processing and higher limits for professional-volume work.
