Zero Upload Privacy Architecture
PixelLocal operates entirely within your browser memory. When you select a photo, your browser decodes and processes the pixel data locally using HTML5 Canvas and WebAssembly. Your files are never transmitted over the internet, logged, or stored on remote servers.
Troubleshooting & Known Limitations
- ⚠️If quality is set too low (e.g. under 30%), visual compression artifacts may appear. Use 70-80% for optimal balance.
