What is WIC?
IMatch supports the Windows Imaging Component (WIC) framework supported in Windows 7, Windows 8, Windows 10 and later versions of Windows.
Windows WIC enables applications like IMatch to work with image formats (including RAW files) via so-called codecs provided by camera vendors, Microsoft or 3rd parties. Without the need to know the internal details of a file format, IMatch can handle the files as long as a working codec is installed.
Please ensure that you have always installed the latest RAW codec (WIC codec) available from your camera vendor’s web site (if your camera vendor supplies WIC codecs for your cameras). This ensures that IMatch can read and reproduce the images with the best possible quality. Camera vendors make changes to their RAW files almost with every camera model. If you work with scanners, microscopes and similar, your hardware vendor most likely also supplies a codec if the scanner emits a proprietary file format.
Note: Do not install multiple codecs from different vendors for the same RAW format. Experience tells that this may lead to more or less subtle problems when processing RAW files.
Windows Built-in WIC Codecs
Current Windows versions include a set of WIC codecs which support a wide range of common RAW formats. Note that not all camera format variants are supported, though.
Over the years, camera vendors introduced dozens of incompatible format variants which all use the same file extension. This complicates the process of providing a WIC codec for all camera models. Contact your camera vendor for assistance if you need more information.
HEIC/HEIF Support on Windows 10 and Windows 11
HEIC is a modern still image / video format mostly used on the Mac platform. In order to process HEIC files in IMatch you need to install a WIC codec. The standard WIC codecs included in Windows 10 don’t support HEIC/HEIF by default.
Microsoft provides a free WIC codec for Windows which adds support for HEIC to the operating system. To find this WIC codec, search for
HEIF Image Extensions on the Microsoft web site or use your favorite search engine. Make sure you install the original codec created by Microsoft.

Note: Windows 11 includes a set of WIC codecs which support a wide variety of RAW formats. If your RAW format is not yet supported, contact your camera vendor and Microsoft for support.
Sadly, as far as we can determine, the only camera vendor who cares enough about their customers to provide an optimized WIC codec is Nikon.
photools.com RAW Processing and LibRAW Support
If no WIC codec is available for one or more RAW variants you use, IMatch uses its built-in RAW processing pipeline based on LibRaw to create thumbnails and cache images. LibRaw is an awesome OpenSource project which is actively maintained and supports hundreds of RAW format variants.
You can also switch to IMatch’s internal RAW processing when the default Windows WIC codec does not support the RAW variant your camera produces or if you experience problems like wrong orientation or similar.
They also offer an excellent and affordable software called FastRawViewer for viewing Raw files on the Mac and Windows.
