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.

What is WEBP?

WebP is a modern image format that provides superior lossless and lossy compression for web images. Developed by Google, it delivers smaller file sizes while maintaining or improving visual quality.

When Should You Use XPM vs WEBP?

Use XPM When...

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

Use WEBP When...

Reach for WEBP when your priority is web images, responsive design, modern websites — its efficient compression makes sharing fast and storage minimal.

XPM vs WEBP: Key Differences

  • •XPM and WEBP diverge on compression: lossless compression for the source, lossy compression for the target.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Alpha channel support: WEBP handles transparency, so semi-transparent pixels from the source will be lost.
  • •File sizes: XPM files typically range Small, efficient for icons and WEBP files 20-40% smaller than equivalent JPEG/PNG.
  • •Primary audience: XPM is built for x11 desktop icons, legacy unix graphics scenarios, while WEBP focuses on web images, responsive design, modern websites — pick the format that matches your output requirement.
  • •WebP achieves 25-34% better compression than JPEG at equivalent quality

Advantages of XPM

  • ✓The lossless nature of XPM means file sizes stay reasonable while handling X11 desktop icons, legacy Unix graphics efficiently.
  • ✓From mobile devices to enterprise servers, XPM is recognized and supported everywhere.
  • ✓The trade-off for XPM's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓XPM is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of WEBP

  • ✓The lossy nature of WEBP means file sizes stay reasonable while handling Web images, responsive design, modern websites efficiently.
  • ✓From mobile devices to enterprise servers, WEBP is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using WEBP thanks to its efficient compression.
  • ✓WEBP is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting XPM to WEBP Conversion

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