VIFF to TAR.BZ2 Converter
Processing entirely on your device — large files may take a moment.
Khoros Visualization Image and Bzip2-compressed Tar exist for different jobs: 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. Produce a TAR.BZ2 when a mirror, build script or legacy toolchain expects the classic .tar.bz2 release artifact.
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.
How VIFF compares to TAR.BZ2
| VIFF | TAR.BZ2 | |

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 TAR.BZ2 format
TAR.BZ2 pairs the tar container with bzip2 compression — the classic release artifact of the 2000s Unix world. Bzip2's block-sorting algorithm compresses text and source trees noticeably tighter than gzip, which is why distribution mirrors and source releases favoured it for years.
Today it has largely ceded the top spot to TAR.XZ (smaller) and tar.gz (faster), but countless build scripts, mirrors and legacy toolchains still expect the exact .tar.bz2 artifact — and producing it is a matter of running the tar through a bzip2 encoder.
+Strengths
- ✓Tighter than gzip on text and source trees
- ✓Classic, universally supported on Unix-like systems
- ✓Deterministic, well-understood artifact for releases
!Limitations
- −Slow compression compared to gzip/zstd
- −Larger than TAR.XZ for the same content
- −Single stream — no random file access
Why convert VIFF to TAR.BZ2?
Converting makes sense where the strengths of TAR.BZ2 meet what VIFF cannot give you. Tighter than gzip on text and source trees Meanwhile Tied to discontinued Khoros tooling One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this VIFF to TAR.BZ2 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 TAR.BZ2?
No — TAR.BZ2 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.
Can I convert several VIFF 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.
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.
