What is PCD?

Kodak Photo CD (PCD) is a high-resolution image format for storing scanned photos on CD, supporting multiple resolutions from thumbnail to 3072x2048.

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 PCD vs XPM?

Use PCD When...

Reach for PCD when your priority is photo cd scanning, legacy photo archiving — its efficient compression makes sharing fast and storage minimal.

Use XPM When...

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

PCD vs XPM: Key Differences

  • •The core technical difference: PCD relies on lossy compression whereas XPM uses lossless compression.
  • •Moving from PCD (lossless) to XPM (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: XPM supports transparency, so alpha information is preserved during conversion.
  • •File sizes: PCD files typically range 4-6MB per image at base resolution and XPM files Small, efficient for icons.
  • •Use case fit: PCD targets photo cd scanning, legacy photo archiving and XPM targets x11 desktop icons, legacy unix graphics — your choice depends on which workflow stage you are serving.

Advantages of PCD

  • ✓The lossy nature of PCD means file sizes stay reasonable while handling Photo CD scanning, legacy photo archiving efficiently.
  • ✓From mobile devices to enterprise servers, PCD is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using PCD thanks to its efficient compression.
  • ✓PCD is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of XPM

  • ✓XPM uses lossless compression tailored for X11 desktop icons, legacy Unix graphics.
  • ✓XPM is supported natively on virtually every device, browser, and operating system.
  • ✓XPM files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓XPM integrates seamlessly with all major creative tools and workflows.

Troubleshooting PCD 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 PCD 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
