About formats

CR2 (Canon RAW version 2) is Canon's second-generation proprietary RAW image format, introduced in 2004 with the EOS-1D Mark II and used across Canon's DSLR lineup until the transition to CR3 beginning in 2018. CR2 files use a TIFF-based container that stores the raw sensor data compressed with a lossless variant of JPEG encoding (Huffman-coded prediction residuals), keeping file sizes manageable while preserving every bit of the original capture. Each CR2 file contains multiple image sections: a small thumbnail, a mid-size preview JPEG suitable for quick review, and the full-resolution RAW data at 14-bit depth on most bodies. The format records extensive shooting metadata including Canon's proprietary tags for lens model, autofocus point selection, Picture Style settings, dust-delete data from the sensor cleaning reference shot, and per-body calibration information. One advantage is the vast software ecosystem — CR2 is one of the most widely supported RAW formats in existence, handled natively by Adobe Lightroom, Capture One, DxO, RawTherapee, darktable, and dozens of other converters and viewers, owing to Canon's dominant market share during the DSLR era. Reliable archival longevity is another key strength: the TIFF-based structure and well-documented layout make CR2 files relatively straightforward to parse even with custom tools, and the format's ubiquity means archival support will persist for decades.

VIFF (Visualization Image File Format) is a scientific image format developed by Khoral Research (originally at the University of New Mexico), first appearing around 1990 with the Khoros visual programming environment for image processing and data visualization. VIFF files use a 1024-byte header followed by optional color map data, and the image data itself, with the header containing detailed specifications: data storage type (bit, byte, short, integer, float, double, complex), data encoding (none, CCITT Group 3/4), color space model (none, generic, RGB, HSI, CMYK, and others), and support for multi-band (multi-channel) images with arbitrary numbers of bands. The format accommodates one-dimensional signals, two-dimensional images, three-dimensional volumes, and location data (sparse pixel coordinates), making it versatile beyond simple image storage. VIFF was designed for the Khoros/VisiQuest visual dataflow programming environment, where users constructed image processing pipelines by connecting processing nodes in a graphical canvas — an approach that influenced later systems like AVS, MATLAB Simulink, and LabVIEW. One advantage is scientific data fidelity: VIFF supports the full range of numeric types used in scientific computing (including complex numbers and double-precision floats), stores multi-band datasets natively, and carries calibration metadata — making it suitable for remote sensing, medical imaging, and spectral analysis applications where generic image formats lose information. The format's connection to the Khoros visual programming paradigm provides another notable dimension — VIFF was the standard I/O format for one of the most influential early visual programming environments for scientific image analysis. VIFF files can be read by ImageMagick and legacy Khoros/VisiQuest installations.

Frequently Asked Questions

Why convert CR2 to VIFF?

Scientific research tools often require VIFF format. Converting your Canon CR2 images makes them accessible to astronomical and lab analysis software.

What programs open VIFF?

Open VIFF with Khoros/VisiQuest, IrfanView, and scientific visualization tools — it works across platforms.

Are CR2 and VIFF the same quality?

CR2 stores raw sensor data while VIFF is a processed format. The conversion produces the best quality VIFF can support from your original RAW data.

Can I convert multiple CR2 photos at once?

Yes — batch upload is supported. Queue several Canon CR2 images and convert them all to VIFF in one session without repeating the process.

Will my CR2 metadata (EXIF) be preserved?

Metadata handling depends on the target format. Where VIFF supports it, camera data like shooting parameters and GPS coordinates can be retained.

Do I need to install software?

No installation required. The CR2 to VIFF converter runs entirely in your web browser — just upload, convert, and download the result.
