## Perguntas frequentes

### What is a WASM file?

WASM (.wasm, WebAssembly) is a binary instruction format for a portable, stack-based virtual machine. It enables code written in C, C++, Rust, Go and other languages to run at near-native speed in web browsers. WASM is used for games, video editing, scientific computing and more.

### Are my WASM files uploaded?

No. Modules you open from your device stay on your device and are parsed locally. Only the public sample module is requested from the server.

### Can I execute WASM modules?

The viewer focuses on inspecting the module structure (sections, imports, exports). Executing arbitrary WASM requires a specific host environment and is not part of the preview functionality.
