About formats

CDT (CorelDRAW Template) is a template file format used by CorelDRAW, Corel Corporation's vector graphics editor available since January 1989. A CDT file is structurally identical to a standard CDR document — sharing the same RIFF-based container, vector object types, color definitions, and page layout capabilities — but is designated as a reusable starting point for new designs rather than a finished artwork file. When opened in CorelDRAW, a CDT creates a new untitled document pre-populated with the template's content, leaving the original template unchanged for repeated use. This workflow mirrors the template model found in office productivity suites, adapted for graphic design. CDT files commonly contain pre-built layouts for business cards, brochures, letterheads, certificates, posters, and other standardized print materials, complete with placeholder text, guide lines, bleed areas, and properly configured color spaces for print output. One advantage is workflow consistency — design teams can distribute branded templates ensuring every new document starts with correct dimensions, margins, fonts, and color palettes aligned to corporate identity standards. The format also saves significant setup time: rather than configuring document properties and recreating layout elements from scratch, designers begin with a production-ready foundation. Corel ships hundreds of CDT templates with CorelDRAW installations, and the format is supported across CorelDRAW versions with the same compatibility considerations as CDR.

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 CDT to VIFF?

CDT files are CorelDRAW-exclusive. Turning them into VIFF images makes the content accessible across all platforms.

How do I open a VIFF file?

VIFF files open in Khoros/VisiQuest imaging suite and ImageMagick with VIFF format support.

Is the conversion process secure?

Your files stay private. CDT uploads are deleted after processing, and converted files are purged within 24 hours.

Can I use this converter on a phone?

Yes. Convertio runs in any mobile browser — upload your CDT file, convert, and download without installing an app.

Will my design look different after conversion?

The output stays true to the original CDT template. Minor differences may occur due to format capability differences.

Can I batch convert CDT files to VIFF?

Yes — upload multiple CDT files at once and Convertio will process them all in a single session.
