Convert IIQ to PS Files Online for Free.

IIQ (Intelligent Image Quality) is the proprietary raw image format used by Phase One digital cameras and digital backs, primarily medium format systems used in professional photography.

This format stores the unprocessed data directly from the camera's image sensor, preserving the maximum amount of information for post-processing flexibility.

IIQ files typically contain significantly more color information and dynamic range than processed formats like JPEG, allowing for extensive adjustments to exposure, white balance, and color without quality degradation.

Phase One offers two variants: IIQ L (Large) which uses lossless compression and IIQ S (Small) which uses lossy compression while still maintaining very high quality, giving photographers options based on their storage and workflow needs.

IIQ files can be opened with Phase One's Capture One software, which is specifically designed to process these raw files with maximum quality and control.

Adobe Camera Raw and Lightroom support IIQ files from supported Phase One cameras, offering an alternative workflow for photographers already using Adobe's ecosystem.

Other professional raw processing applications like DxO PhotoLab, ON1 Photo RAW, and Exposure X may support IIQ files from certain Phase One camera models.

For preview purposes, some general image viewers and operating systems may display the embedded JPEG preview in IIQ files, but cannot access or process the raw data itself.

To convert IIQ files to more widely compatible formats like TIFF, JPEG, or PNG, use our specialized raw converter that preserves the image quality while making it more accessible.

For the highest quality processing and conversion, Phase One's Capture One software offers advanced tools specifically optimized for IIQ files with precise control over all aspects of the image.

When converting from IIQ to other formats, consider 16-bit TIFF for maximum quality retention or DNG (Digital Negative) format to maintain raw processing capabilities in other software.

For web sharing or client previews, converting to standard formats like JPEG with appropriate color space selection (sRGB for web use) ensures proper display across different devices.

PS (PostScript) is a page description language developed by Adobe that describes the appearance of text, graphics, and images on a printed page. It was revolutionary in desktop publishing and printing industries.

Unlike EPS, which is a single graphic, PS files can contain multiple pages and are primarily used for printing documents rather than for embedding graphics into other documents.

PostScript files contain programming instructions that describe precisely how text and graphics should appear on a page, enabling consistent reproduction across different printers and devices.

PS files can be viewed and printed using software like Adobe Acrobat Distiller, Ghostscript with GSview, or PostScript viewers.

For macOS users, Preview can open many PostScript files, rendering them for on-screen viewing.

Some professional printing software packages also support direct import and processing of PostScript files.

To convert PS files to more widely supported formats like PDF, use our online converter that maintains all text, graphics, and layout elements from the original PostScript file.

Converting PS to PDF is the most common conversion path, as PDF preserves all PostScript elements while adding features like compression and web compatibility.

For image-based outputs like PNG or JPG, our converter will rasterize the PostScript content at your specified resolution.
