IIQ to PCT conversion is the process of transforming an IQ180 raw image file (IIQ), typically produced by Phase One digital medium format cameras, into a PCT (Macintosh Picture) file, a Mac OS native image container that can store bitmap and PICT-style graphics. This conversion decodes the camera-specific raw sensor data, applies color and exposure interpretations, and writes the resulting raster image into the PCT format for compatibility with macOS apps and legacy workflows.

IIQ files use the MIME type image/x-phaseone and contain raw sensor data requiring specialized codecs for processing. PCT files typically use the MIME type image/pict and are associated with QuickDraw and related codec systems for rendering. Converting IIQ to PCT involves decoding raw data into a raster format suitable for display and editing in common applications.
The PCT (.PCT) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like IIQ.
While specific technical details aren't available here, PCT files generally serve the purpose of storing image effectively within their domain.
Easily convert your IIQ files to PCT format with our efficient online converter. Designed for seamless conversions, our tool supports all major browsers and preserves image quality while changing formats.
IIQ files are proprietary raw image formats used primarily by Phase One cameras, containing unprocessed sensor data. PCT files are versatile image formats often used in Macintosh systems for storing high-quality graphics. While IIQ files offer maximum detail for photographers, PCT files provide broader software compatibility and easier integration into documents.
Keep individual IIQ files under 250MB for free web converters; for large medium-format IIQ files, use desktop tools to avoid upload limits.
To preserve quality, export to PCT with 16-bit per channel and embed the original ICC/profile (ProPhoto or camera profile) rather than forcing 8-bit sRGB.
Batch conversion: use a desktop app or command-line tool that supports IIQ metadata and parallel processing when converting many large IIQ files to avoid timeouts.
Be aware that PCT is a macOS/legacy-focused container; some modern Windows applications may not fully support embedded ICC profiles or high bit depths in PCT.

If you rely on raw-specific edits (exposure recovery, highlight reconstruction), finalize those in a raw processor before converting, because PCT stores rasterized results not raw sensor data.
