When Should You Use XWD vs AVIF?

XWD vs AVIF: Key Differences

• •The core technical difference: XWD relies on lossless compression whereas AVIF uses lossy compression.
• •Moving from XWD (lossy) to AVIF (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: AVIF does not support alpha channels — transparent areas in the source will become opaque.
• •XWD files are typically Similar to uncompressed PNG while AVIF files range 40-50% smaller than JPEG/PNG
• •Use case fit: XWD targets x11 screenshots, remote display capture and AVIF targets modern web, next-generation web applications — your choice depends on which workflow stage you are serving.
