Magic under the hood.
Simple on the outside.
No complex settings required. Just drop your files and watch your free space grow.
Drop Your Files
Drag and drop folders, documents, photos, or entire game directories into the app.
Smart Analysis
The Wizard analyzes each file to determine the optimal, 100% lossless compression strategy.
Reclaim Space
Files are shrunk in place. They look and act exactly the same, but take up significantly less space.
Advanced, 100% Lossless Technology
We never degrade your data. Every byte is perfectly preserved.
Transparent OS Compression
Utilizes built-in Windows (LZX, XPRESS) and macOS (LZFSE, ZLIB, LZVN) filesystem compression. Files remain fully accessible to all apps without needing to be extracted.
Pixel-Perfect Image Optimization
Optimizes JPEGs and PNGs by reorganizing their internal data structure without altering a single pixel or changing the file format. All metadata is preserved by default.
JPEG XL Transcoding
Convert standard JPEGs to the next-generation JPEG XL format, achieving 20-30% smaller file sizes with strict mathematical losslessness. All metadata is preserved by default.
Windows CompactOS
Instantly reclaim 1GB to 3GB of disk space by compressing Windows system files safely and reversibly.
Metadata Preservation
By default, all EXIF data, ICC color profiles, and timestamps are carefully preserved during optimization.
100% Reversible
Want to undo it? Drop previously compressed items into the Decompress tab to return them to their exact original state.

Frequently Asked Questions
Yes. We strictly adhere to lossless compression techniques. Transparent OS compression operates at the filesystem level, meaning the files themselves are mathematically identical when read by any application. Our image optimization tools utilize lossless re-encoding, preserving every single pixel exactly as it was.
Surprisingly, it often makes it faster. Because the compressed files are smaller, your hard drive spends less time reading data. Modern CPUs decompress this data in RAM almost instantly, resulting in an overall faster read operation for most files.
The app will continue to work, but at a "throttled" speed. Batch processing will be slowed down significantly with processing delays, and you will see prompts to upgrade to Pro. You can always decompress files for free, regardless of limits.
YES! You can absolutely drop the Shrink Wizard application into itself to compress it. It's a fun way to test the magic immediately.
