VICAR to XBM Converter
Processing entirely on your device — large files may take a moment.
Convert XBM icons to PNG for viewing, or emit XBM when embedded firmware/Unix code needs a compiled-in bitmap. 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.
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.
How VICAR compares to XBM
| VICAR | XBM | |
|---|---|---|
| Structure | VICAR Planetary Image coder | C #defines + hex byte array |
| Compatibility | ImageMagick, specialty tools | X11, C compilers, GTK |
| Best for | Legacy and specialty pipelines | Compiled-in cursors and icons |

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 XBM format
XBM is the most honest image format ever shipped: the "file" is a C source array of hex bytes, compiled straight into X11 applications as cursor and icon bitmaps. Rendered, it is 1-bit black and white — the ancestors of every pixel-art cursor you still use.
Because it compiles, XBM never died: firmware UIs, embedded icons and retro Unix tooling still want it. Converting a PNG down to XBM gives embeddable, compilable art; the other direction previews what the C array actually draws.
+Strengths
- ✓Compiles directly into C/C++ programs
- ✓Zero-payload format — text only
- ✓Still required by embedded and Unix tooling
!Limitations
- −1-bit black & white only
- −Human-hostile representation
- −X11 bit order trips up hand-rolled decoders
Why convert VICAR to XBM?
Think of it as moving your file to the container that fits the job. Niche format — few modern readers XBM works differently: Compiles directly into C/C++ programs If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this VICAR to XBM 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 XBM?
No — XBM 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.
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.
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.
