Illustrative Compression Example
Illustrative benchmark: A sample 2.8 MB high-resolution smartphone JPEG photo compressed at 75% quality typically reduces to approximately 420–600 KB — achieving substantial storage and bandwidth savings while remaining visually crisp on standard screens (actual reduction varies based on image complexity and original compression).
Technical Limitations & Boundaries
- Lossy compression: Reducing quality below 50% may introduce visible JPEG/WebP compression artifacts on sharp text edges.
- PNG transparency: Compressing PNG files converts them to WebP to preserve alpha transparency with high efficiency.
- Zero upload: Because files never leave your computer, compression speed depends entirely on your local CPU and GPU.
