VIFF to RAS Converter
Processing entirely on your device — large files may take a moment.
VIFF is the image format of the Khoros software system, a research toolkit from the early days of scientific visualization. Still found in legacy academic image-processing datasets. Convert to RAS for legacy UNIX image archives.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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
About the RAS format
The Sun Raster coder of the ImageMagick set — the unix-archive 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
Why convert VIFF to RAS?
Think of it as moving your file to the container that fits the job. Tied to discontinued Khoros tooling RAS works differently: Written natively by ImageMagick If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this VIFF to RAS 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 VIFF to RAS?
No — RAS is a lossless format, so every pixel of the converted image matches your original VIFF 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 VIFF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to RAS?
Transparency is kept whenever RAS actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
