Most image tools upload your data to their servers. We don't. Here is the technical explanation of how SnapResizer protects your visual data.
Your images never touch our servers. Processing occurs entirely in your browser's local memory. We don't just "encrypt" your data; we never receive it in the first place.
We leverage WebAssembly (WASM) and specialized browser APIs to perform heavy graphics computation locally on your CPU and GPU.
Once you close your browser tab, all session data related to your images is automatically cleared by the browser's Garbage Collection system.
Our core compression and cropping logic is written in C++ and compiled to WASM. This allows us to run high-performance algorithms at native speeds directly within the browser sandbox.
We utilize worker threads to process images in the background, ensuring your interface remains smooth and responsive while handling even the largest 4K photographs.
By operating within the standards-compliant browser sandbox, we are restricted from accessing any file on your system unless you explicitly select it via the upload dialog.
// Initialize WASM Container
import { initWasm, processImage } from "./privacy-engine";
// Processing local file buffer...
const buffer = await file.arrayBuffer();
const result = await processImage(buffer);
// Success: Data never left localhost
Status: Secure Local Processing Complete
"The safest way to protect user data is to never ask for it. Every line of code in SnapResizer is written with the assumption that your photos are private, personal, and strictly yours."
