Are my files uploaded to any server?

No. Docuboxer uses WebAssembly to process everything locally in your browser. Your files never leave your device.

WebAssembly (Wasm) is a technology that runs high-performance code directly in the browser at near-native speeds. Docuboxer uses Wasm for PDF compression, image processing and more.

Does Docuboxer work without internet?

Yes. Once the page has loaded, most tools work offline. Only the AI features need a connection.

How Docuboxer works

99% of the tools on the internet run on the traditional client-server model. You upload your file, wait while it travels across the internet, it gets processed on the company's server, and you download the result.Docuboxer does not work that way.

The Zero-Server model

We rewrote the paradigm. When you open any tool on Docuboxer, we download the processing engine straight to your browser in milliseconds. When you drag a file onto the screen, it never leaves your computer.

Traditional model

You upload the file (slow).
You wait in the server queue.
The server reads your private information.
The file gets processed.
You download the result (slow).

Docuboxer (Local)

You drop the file.
It is processed instantly on your CPU.
Done.

WebAssembly (Wasm)

To make this possible, we use WebAssembly. It is a technology that lets us run high-performance code (such as PDF compression libraries written in C++ or Rust) directly inside Google Chrome, Safari or Firefox at near-native speeds. That means your browser becomes a small but powerful server dedicated exclusively to your tasks.

Absolute, verifiable privacy

Since there is no communication with a backend server at processing time, the privacy of your data is guaranteed by the very architecture of the system. You can switch off your Wi-Fi after the page loads and Docuboxer will keep working perfectly. Your confidential documents, invoices and personal photos are safe from security breaches and from AI training datasets.
