为什么要转换
Why convert DNG to JXL
02
Broader cross-platform support
JXL is accepted by a wider range of image viewers, editors, and content systems than DNG. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Portable, predictable file format
JXL is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

质量与保真度
质量与保真度
- Lossless to lossless: conversion is mathematically reversible in principle.
- Target supports alpha but the source has none, so the output is fully opaque.
- Metadata (EXIF/tags) is preserved where the source provides it.
- JXL can be lossy or lossless — switch modes for pixel-perfect output if needed.
