Which MIME types are related to file extension ".iiq"?
The .iiq file extension is associated with 6 MIME types:
image/x-raw-phaseone, image/x-minolta-mrw, image/x-nikon-nef, image/x-olympus-orf, image/x-pentax-pef, image/x-sony-srf.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .iiq Files
IIQ files are raw image files used by Phase One cameras. They store unprocessed sensor data that allows for high quality editing and print production.
- Format type: Camera raw image format with MIME type image/x-raw-phaseone.
- Main purpose: Capture full sensor data for detailed post-processing.
- Software: Open these files using dedicated raw processing apps like Capture One, Adobe Lightroom, or Photoshop with raw plug-ins.
- Similar formats: They belong to the same family as other camera raw files such as Nikon’s NEF, Olympus’ ORF, Pentax’s PEF, Sony’s SRF, and Minolta’s MRW.
- Key benefit: They preserve intricate image details by storing data directly from the camera sensor.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .iiq file?
An IIQ file is a proprietary raw image format created by Phase One high-end digital camera backs. It stores unprocessed data directly from the image sensor, designed to provide maximum flexibility for professionals adjusting exposure, white balance, and color grading.
How do I open an IIQ file on my computer?
The native software for IIQ files is Capture One, which offers the most accurate rendering for Phase One cameras. Alternatively, you can open and edit these files using Adobe Lightroom, Adobe Photoshop (via Camera Raw), or free viewers like IrfanView (with plugins installed).
How can I convert IIQ files to JPEG?
You cannot simply rename the file; you must use raw processing software to 'develop' and export it. In Capture One or Lightroom, open the image and select the Export or Save As option to convert the raw data into a standard JPEG or TIFF image.
What is the difference between IIQ L and IIQ S?
Phase One cameras typically offer two recording modes for the .iiq extension: IIQ L (Large), which is a completely lossless format, and IIQ S (Small), which uses an intelligent compression algorithm to significantly reduce file size while retaining near-perfect image quality.
What is the MIME type for IIQ files?
The standard MIME type associated with Phase One raw images is image/x-raw-phaseone. For more information on raw image media types, visit mime-type.com.
Why does my IIQ file look different in different software?
Raw files require interpretation by a raw engine, and different software (e.g., Capture One vs. Adobe Camera Raw) applies different default color profiles and sharpening algorithms. Capture One generally provides the manufacturer-intended look for Phase One files.
Can I convert IIQ files to DNG?
Yes, you can use the free Adobe DNG Converter to transform proprietary .iiq files into the universal DNG (Digital Negative) format. This is helpful for archiving or if you need to open the files in older software that doesn't support the specific camera model.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
