JXL to PNG Converter
Decode JPEG XL to full-resolution PNG or APNG while preserving alpha, bit depth, color profiles, and every animation frame when representable.
Reconstruction is not re-encoding
A JPEG-derived JXL can store the original JPEG structure. Reconstruction restores those exact original bytes. A new JPG encode decodes pixels and compresses them again, so its bytes and pixels may differ.
Format limits stay explicit
PNG and JPG cannot represent every JPEG XL HDR signal, extra channel, animation feature, or metadata box. Animated JXL is never sent to JPG, and animated PNG output uses APNG so frames are not silently discarded.
