VICAR to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. If your files are still in VICAR format, this page is the shortcut: VICAR is NASA/JPL's planetary image format — Mars rover and Voyager frames circulate in it, with a label block describing the instrument.
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 XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert VICAR to XZ?
There is a concrete reason this conversion exists: Niche format — few modern readers XZ sidesteps that — Highest common ratio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this VICAR to XZ 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 XZ?
No — XZ 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 about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the VICAR file.
Are the files inside my VICAR archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
