Storing large image libraries can be challenging, especially when you want to maintain access to your original files without sacrificing quality for storage. Zero Loss Compress offers a practical solution by using JPEG XL, a modern image format designed for efficiency and flexibility.

JPEG was first introduced in 1992. Today’s advancements in compression techniques allow us to optimize JPEGs even further while keeping access to the original data. This process is fully reversible, with no loss of quality.

JPEG XL offers up to 20% additional compression over standard JPEG files, while retaining the ability to revert to the original format at any time. This makes it an ideal choice for long-term photo storage without compromising image quality or integrity.

Batch Processing

The application supports batch processing and can process hundreds of files in a row when selecting a folder.

Convert .jxl files back to JPEG

The app can convert .jxl files to .jpg files and vice versa.

Reversible Conversion

The original JPEGs are always preserved. If necessary, you can easily revert back to them with no loss of quality.
