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.

PAL is a 16-bit per pixel interleaved YUV image format that stores color information using a luminance-chrominance model rather than direct RGB values. Each pixel pair is packed into four bytes using the UYVY byte ordering — U (Cb), Y0, V (Cr), Y1 — where two adjacent pixels share a single set of chroma (color difference) samples while each retaining its own luminance (brightness) value. This 4:2:2 chroma subsampling halves the color resolution horizontally with negligible perceptual impact, since human vision is far more sensitive to brightness variations than color detail. The format traces its conceptual roots to analog broadcast television standards developed during the 1960s and 1970s, where separating luminance and chrominance enabled backward-compatible color transmission alongside existing monochrome signals. In digital imaging, 16-bit YUV serves as a common intermediate representation for video capture hardware, frame grabbers, and image processing pipelines that work in the YCbCr color space internally before converting to RGB for display. One advantage is bandwidth efficiency: at 16 bits per pixel, UYVY requires roughly two-thirds the data of uncompressed 24-bit RGB while preserving virtually identical perceived quality, making it well suited for high-throughput video capture and real-time image processing applications. The format's direct correspondence to how video hardware captures and outputs data provides another practical benefit — many capture cards and camera sensors natively produce UYVY data, so storing it in PAL form avoids an unnecessary color space conversion step that would add latency and introduce rounding artifacts.

Frequently Asked Questions

Why convert IIQ to PAL?

IIQ is a professional medium format RAW that few tools outside Capture One support. Converting to PAL makes your photos universally accessible.

What opens PAL?

Image processing tools and palette editors open PAL format files.

Does conversion lose image quality?

Some quality depends on the target format. PAL uses palette-based encoding, so results reflect the characteristics of PAL output.

Do I need to install anything?

No installation at all. The IIQ to PAL converter runs entirely in your web browser — just visit the page and start converting.

Is it free to convert IIQ to PAL?

Basic IIQ to PAL conversions are free. Paid plans unlock priority processing and expanded capabilities for heavy users.
