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 APNG?

Animated PNG (APNG) extends the PNG format with frame-based animation support while maintaining full backward compatibility with standard PNG decoders.

When Should You Use XBM vs APNG?

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 APNG When...

Reach for APNG when your priority is web animations, game sprites, animated icons — its uncompromising quality ensures every detail is preserved.

XBM vs APNG: Key Differences

  • •The core technical difference: XBM relies on lossless compression whereas APNG uses lossless compression.
  • •Since both XBM and APNG use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •How transparency is handled: APNG supports transparency, so alpha information is preserved during conversion.
  • •Storage footprint: Very small, minimal overhead for XBM vs Larger than GIF but better quality for APNG.
  • •Primary audience: XBM is built for x11 icons, monochrome graphics, embedded ui scenarios, while APNG focuses on web animations, game sprites, animated icons — pick the format that matches your output requirement.

Advantages of XBM

  • ✓XBM applies lossless compression specifically calibrated for X11 icons, monochrome graphics, embedded UI.
  • ✓XBM enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓XBM guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find XBM support built into virtually every tool that handles X11 icons, monochrome graphics, embedded UI — no plugins or converters needed.

Advantages of APNG

  • ✓APNG applies lossless compression specifically calibrated for Web animations, game sprites, animated icons.

Troubleshooting XBM to APNG Conversion

  • !Converting XBM to APNG gives blurry output → increase the quality setting before conversion
  • !Colors look different in APNG than XBM → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → APNG uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in XBM turned white in APNG → APNG may not support transparency
