How to Convert Files

Convert VIFF Khoros visualization images to and from common formats in your browser, with all processing done locally on your device.

What a VIFF file holds

VIFF is the Khoros Visualization Image File Format, the native image format of the Khoros scientific data-visualisation and image-processing system. It was built to store not just ordinary pictures but multidimensional scientific image data.

Reflecting its scientific purpose, VIFF can hold multiple data bands and various numeric data types, along with a detailed header describing the structure. This let researchers store the kind of multi-band and high-precision imagery that arises in remote sensing and analysis, which simple picture formats cannot represent.

Strengths and limits

VIFF's strength is its capacity for rich scientific data: multiple bands, flexible data types, and descriptive metadata suit visualisation and analysis workflows where accuracy and structure matter.

That richness ties it to the Khoros system and similar tools; it is unfamiliar to mainstream image software and not intended for casual viewing or sharing. Results are converted to standard formats for presentation, accepting that some scientific detail may not carry over.

Origin and Development

VIFF was developed by Khoral Research in the early 1990s as part of the Khoros scientific data-visualization system. The format was created to address the need for a robust method to store and manipulate multidimensional scientific image data, which traditional formats could not adequately support. VIFF's design incorporates multiple bands and data types, making it suitable for complex visualizations.

Over time, VIFF gained traction in scientific and remote sensing communities due to its ability to handle diverse datasets. Tooling around VIFF has evolved, with various software packages providing support for reading and writing the format. While it remains less common than mainstream image formats, its specialized capabilities have led to its adoption in niche applications and research environments, reinforcing its role in scientific workflows.

Choosing VIFF Wisely

Select VIFF when working with multi-band scientific data that requires precise representation and extensive metadata. It is particularly useful in fields such as remote sensing, medical imaging, and environmental studies. VIFF's uncompressed nature ensures data integrity, making it preferable for applications where accuracy is critical. However, be aware of file size implications when handling large datasets.

When converting to or from VIFF, ensure that your tools support the format's multi-band structure and data types. Some common image processing libraries may not fully support VIFF, leading to potential data loss or misinterpretation. Use dedicated scientific visualization software for best results. Additionally, consider the metadata requirements of your project, as VIFF allows for extensive descriptive information that may be lost if not handled correctly.

Working with VIFF files

You will encounter VIFF in scientific computing and remote-sensing archives connected to the Khoros system.

For analysis, keep the data in a format that preserves its precision and bands, such as multi-band TIFF. For figures and sharing, convert a single visualised band or a colour composite to PNG for reliable display.
