VICAR to VIFF Converter
Processing entirely on your device — large files may take a moment.
VICAR Planetary Image and Khoros Visualization Image exist for different jobs: VICAR is NASA/JPL's planetary image format — Mars rover and Voyager frames circulate in it, with a label block describing the instrument. Convert legacy VIFF datasets to PNG for modern viewing and notebooks.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the VICAR format
The VICAR Planetary Image coder of the ImageMagick set — the planetary-science format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
About the VIFF format
VIFF is the image format of the Khoros software system, a visual-programming environment built for scientific image processing in the late 1980s and 1990s. Its files carry raster data plus optional attribute lists, and it survives today mostly in older academic datasets and image-processing course material.
Modern software rarely opens VIFF without help. Converting VIFF to PNG puts legacy research imagery into a format every viewer, notebook and browser understands — useful when reviving old datasets or coursework.
+Strengths
- ✓Holds multi-band scientific raster data
- ✓Attribute lists travel with the image
- ✓Simple, fully documented binary layout
!Limitations
- −Tied to discontinued Khoros tooling
- −No browser or OS support
Why convert VICAR to VIFF?
There is a concrete reason this conversion exists: Niche format — few modern readers VIFF sidesteps that — Holds multi-band scientific raster data If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this VICAR to VIFF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting VICAR to VIFF?
No — VIFF is a lossless format, so every pixel of the converted image matches your original VICAR file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your VICAR files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several VICAR files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
