XBM to FARBFELD Converter
Processing entirely on your device — large files may take a moment.
X BitMap and Farbfeld Lossless Image exist for different jobs: XBM is a bitmap stored as C source code — literally an array of hex bytes that a C compiler includes. It was the original X11 icon format, and it still compiles. Convert to Farbfeld for pipelines that want dead-simple lossless pixels.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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
About the FARBFELD format
The Farbfeld Lossless Image coder of the ImageMagick set — the lossless-pixel 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 XBM to FARBFELD?
There is a concrete reason this conversion exists: 1-bit black & white only FARBFELD sidesteps that — Written natively by ImageMagick If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this XBM to FARBFELD 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 XBM to FARBFELD?
No — FARBFELD is a lossless format, so every pixel of the converted image matches your original XBM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to FARBFELD?
Transparency is kept whenever FARBFELD 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.
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 XBM files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
