Why client-side RW2 image compression keeps your photos private
Every pixel of your RW2 images is processed within your browser's WebAssembly sandbox when using ezyZip. Here is why local image compression is technically superior:
- Desktop-Class EngineThe Emscripten-compiled image processing engine runs the same class of algorithms used by professional desktop tools — including advanced quantization, chroma subsampling, and progressive encoding — entirely within isolated browser memory.
- Multiple Compression ModesChoose between quality-based, percentage-based, or target-size compression. Each mode uses a different optimization strategy to balance visual quality against file size for your specific needs.
- Efficient Batch DownloadsCompressed outputs are staged through the Origin Private File System for efficient batch downloading. Process and download hundreds of images in a single operation without repeated file-picker interactions.
- Automatic CleanupSession cleanup ensures processed image data does not persist beyond your active browser session. Temporary files in the Origin Private File System are automatically purged when stale, keeping your browser storage clean.
