How do I convert an ICO file to XBM using this converter?

Upload your ICO file by clicking the file selection button. Choose 'XBM' as the target format from the drop-down menu. Adjust any settings such as resolution or color mode if needed (XBM is monochrome). Then click 'Convert'. Once the conversion finishes, download the XBM file. You can also drag-and-drop multiple ICO files for batch conversion.

Why would I need to convert an ICO file to XBM?

XBM (X BitMap) is a monochrome bitmap format used primarily in X11/X Window System and Unix-like environments. Unlike ICO files which are multi-resolution and support transparency, XBM files are simple C source code arrays, making them extremely lightweight for small icons and cursors in legacy Linux software. Converting to XBM allows you to use the image in low-level toolkits, embedded systems, or any place where a compact, machine-readable monochrome graphic is required.

What happens to transparency and color depth when converting ICO to XBM?

XBM is strictly a monochrome (1-bit) format, so all color and alpha information is lost—it is converted to black-and-white based on luminance and threshold settings. During conversion, the ICO's primary frame (or selected size) is rendered, and transparency is handled by treating fully transparent pixels as background color (usually white). Partial transparency is dithered or approximated. The resulting XBM file is a static C header with bit data, so all multi-resolution frames in the ICO are reduced to a single bitmap size. If you need to preserve transparency or color, consider converting to XPM or PNG instead.
