Privacy by Architecture
We don't just promise privacy; we've built a system where data storage is technically impossible.
Zero Server Side Processing
Unlike 99% of online tools, ToolBox Co. doesn't have a backend that processes your files. Every transformation—whether it's compressing an image or formatting JSON—happens entirely inside your browser's V8 Engine.
Local-Only Data Flow
When you upload a file, it never leaves your computer. The 'upload' is actually just a browser memory pointer to your local disk. No packets containing your sensitive data are ever sent over the network.
No Database, No Logs
We do not maintain a database for user submissions. We don't log your IP address against the files you process. Our infrastructure is 'Stateless' by design.
Open & Auditable
You can verify this yourself: Open the Network Tab in your DevTools (F12) while using any of our tools. You will notice zero network activity when you hit 'Convert' or 'Format'.
Technical Deep Dive
When you use a tool like HEIC to JPG, the conversion logic is loaded as a WebWorker into your browser's memory. The worker processes the raw byte array of your image using locally-compiled WASM (WebAssembly) or JavaScript.
Once the process is complete, the browser generates a blob: URL which points to the result in your local RAM. When you click 'Download', the browser simply exports that local RAM reference back to your file system. Total distance traveled by your data: 0 miles.
