Zero Loss Compress
Zero Loss Compress is a macOS utility from EditingTools.io that converts JPEG photos to JPEG XL to save disk space while preserving original image data.
What is Zero Loss Compress?
Zero Loss Compress is a native macOS utility for reducing the storage size of JPEG photo libraries without giving up access to the original image data. It is designed for people who archive large collections of photos and want a smaller on-disk footprint while keeping image quality intact. The app converts JPEG files into JPEG XL (.jxl), a reversible format intended for efficient storage rather than everyday sharing. It supports working with .jpg and .jxl files, lets you keep original files alongside converted copies, and can save output to a folder you choose. The app also offers favorite folders for faster repeat jobs and works offline, which fits privacy-conscious local workflows. Published by EditingTools.io, Zero Loss Compress is best suited to Mac users who want a focused storage utility rather than a full photo management app.

Safety overview
Status: Safe
This app’s file access is consistent with its purpose because it needs access to the photos you choose for conversion. Its offline workflow is a practical privacy advantage for users who prefer local processing. Removing the app does not affect macOS, but you may lose a convenient way to convert JPEG XL files back for workflows that do not support that format.
Recommendation: Keep Zero Loss Compress if you actively archive large JPEG libraries and want a simple local tool for reversible compression. If you no longer use JPEG XL in your workflow, you can remove the app without affecting the rest of your Mac.
