Learn how SnapWap compresses images 100% locally in your browser with zero server uploads.
No. Absolutely zero bytes of your image data are ever uploaded to any remote server or third-party service. SnapWap executes all image decoding, resizing, color quantization, and re-encoding 100% inside your device's web browser using native-speed WebAssembly (WASM) and Web Workers. Your files never leave your local machine.
