JPC to XBM Converter
Processing entirely on your device — large files may take a moment.
JPC is the raw JPEG 2000 code stream — the same wavelet-compressed image data as JP2 without the container box. Common in broadcast and archival pipelines that stream codestreams directly. Convert XBM icons to PNG for viewing, or emit XBM when embedded firmware/Unix code needs a compiled-in bitmap.
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.

About the JPC format
JPC is JPEG 2000 stripped to its bare codestream: the same wavelet-compressed image data as JP2, minus the container boxes that give JP2 its metadata, color profiles and file signature. Broadcast and archival systems that stream codestreams directly (rather than storing boxed files) work with JPC.
Because there is no container, JPC carries no thumbnail, no EXIF and no declared colorspace — players must probe the codestream header itself. Converting JPC into JP2 restores a full container; converting to JPG or PNG produces an instantly viewable copy.
+Strengths
- ✓Wavelet compression, better per-byte quality than JPG
- ✓True lossless mode available
- ✓Streamable — no container parsing needed
!Limitations
- −No metadata, color profile or thumbnail
- −Browsers cannot open it at all
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 JPC to XBM?
There is a concrete reason this conversion exists: No metadata, color profile or thumbnail XBM sidesteps that — Compiles directly into C/C++ programs If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this JPC 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 JPC to XBM?
No — XBM is a lossless format, so every pixel of the converted image matches your original JPC file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to XBM?
Transparency is kept whenever XBM 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.
Can I convert several JPC 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.
