X Window Dump (XWD) is the native screenshot format for X11 windowing systems, capturing pixel data from X displays.

What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

When Should You Use XWD vs HEIC?

Use XWD When...

Reach for XWD when your priority is x11 screenshots, remote display capture — its uncompromising quality ensures every detail is preserved.

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

XWD vs HEIC: Key Differences

  • •XWD and HEIC diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from XWD (lossy) to HEIC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: HEIC does not support alpha channels — transparent areas in the source will become opaque.
  • •File sizes: XWD files typically range Similar to uncompressed PNG and HEIC files 50% smaller than equivalent JPEG.
  • •Primary audience: XWD is built for x11 screenshots, remote display capture scenarios, while HEIC focuses on ios photography, mobile devices — pick the format that matches your output requirement.

  • ✓XWD files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓XWD integrates seamlessly with all major creative tools and workflows.

Advantages of HEIC

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