What is XBM?

X BitMap (XBM) is a monochrome image format that stores pixel data as C source code, commonly used for X11 cursor and icon bitmaps.

What is XPM?

X PixMap (XPM) is a color image format for X11 GUI icons, storing pixel data as C source code with color-key transparency.

When Should You Use XBM vs XPM?

Use XBM When...

Reach for XBM when your priority is x11 icons, monochrome graphics, embedded ui — its uncompromising quality ensures every detail is preserved.

Use XPM When...

Reach for XPM when your priority is x11 desktop icons, legacy unix graphics — its uncompromising quality ensures every detail is preserved.

XBM vs XPM: Key Differences

  • •XBM and XPM diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: Transparent pixels supported via color key
  • •Storage footprint: Very small, minimal overhead for XBM vs Small, efficient for icons for XPM.
  • •Primary audience: XBM is built for x11 icons, monochrome graphics, embedded ui scenarios, while XPM focuses on x11 desktop icons, legacy unix graphics — pick the format that matches your output requirement.

Troubleshooting XBM to XPM Conversion

  • !XPM shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted XPM image looks washed out → the source XBM likely uses a wider color space than XPM supports
  • !XPM file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted XPM looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
