Drop .jxl files for conversion out, or drop JPG/PNG/WebP for encoding to JXL.
libjxl compiled to WebAssembly handles both encode and decode. JXL encode runs slower than other formats — 2–5 seconds per image for high-quality settings.
JXL to JPG/PNG/WebP for universal compatibility. Other formats to JXL for maximum compression or archive use.
