Frequently Asked Questions

Is it safe to view SQLite files online here?

Yes. KNothing uses **WebAssembly (WASM)** to process your .db files **100% locally** within your browser. No data is ever uploaded to a server.

What file formats are supported?

The viewer supports standard **SQLite database files**, typically with extensions like **.db, .sqlite, .sqlite3**, and .db3.

Do I need to install any software?

No. This is a purely **web-based tool**. You can open and analyze your database files directly in your modern web browser (Chrome, Edge, Firefox, Safari) without installing anything.

Can I run SQL queries on my database?

Yes. We provide a full **SQL Query Editor** where you can write and execute custom `SELECT` statements to filter and analyze your data.

Does this SQLite Viewer work offline?

Yes, KNothing is a **Progressive Web App (PWA)**. Once loaded, you can disconnect from the internet and still query your database files securely.
