# ToolsCanvas — Free Browser-Based Utility Tools

> 20 powerful tools that run 100% in your browser. No uploads. No accounts. No cost. Your files never leave your device.

## Why ToolsCanvas is different

Most online tools upload your files to a server, process them remotely, and return the result. ToolsCanvas does the opposite: every tool runs entirely inside the user's web browser using JavaScript, WebAssembly, and modern browser APIs. This means:

- **Zero privacy risk** — files are never transmitted over the network
- **Works offline** — once the page loads, no internet connection is needed for processing
- **Instant results** — no upload/download round-trip latency
- **Free forever** — no server costs means no reason to charge
