XBM to DCX Converter
Processing entirely on your device — large files may take a moment.
X BitMap and Multi-page PCX 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 images to DCX for legacy fax/document archives.
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.
How XBM compares to DCX
| XBM | DCX | |
|---|---|---|
| Structure | C #defines + hex byte array | Multi-page PCX coder |
| Compatibility | X11, C compilers, GTK | ImageMagick, specialty tools |
| Best for | Compiled-in cursors and icons | Legacy and specialty pipelines |

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 DCX format
The Multi-page PCX coder of the ImageMagick set — the fax-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 XBM to DCX?
Converting makes sense where the strengths of DCX meet what XBM cannot give you. Written natively by ImageMagick Meanwhile 1-bit black & white only One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this XBM to DCX 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 DCX?
No — DCX 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.
Can I convert several XBM 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.
Will transparent areas survive the conversion to DCX?
Transparency is kept whenever DCX 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.
