Image2JXL — Lossless JPEG to JPEG XL Conversion on Mac
· 5 min read
Image2JXL is a native macOS app for local JPEG XL conversion, with a focus on JPG to JXL workflows. For JPEG input, it supports reversible JPEG transcoding, so a supported JPG can be stored as a JXL file and restored back to JPG later.
It is useful if you want a local tool for batch organization, archive workflows, and testing JPEG XL without uploading files or relying on a cloud converter.
