Offline and Private Data Tools

Offline: free tools and step-by-step guides in one place. Everything runs in your browser and nothing is uploaded.

Overview

Data Utility runs in your browser, so it can run without a network too. Install it as an app and store the larger engines once, and every tool works offline, on corporate VPNs and on air-gapped machines.

This hub collects the guides and tools for private, offline data work. Your files are processed on your own device and are never uploaded.

Free tools

Open a tool and drop in your file. Nothing is uploaded.

Guides
