Is my database file uploaded anywhere?

No, the file is read and processed entirely in your browser using WebAssembly — it never leaves your device.

Can I save changes back to the file?

No, this is a read-only viewer. Query results and edits exist only in memory for the current session.

What file formats are supported?

Any standard SQLite database file, typically with a .sqlite, .db, or .sqlite3 extension.

How large a database can I open?

The whole file is loaded into browser memory, so very large databases (100+ MB) may be slow or exceed available memory.

Can I export query results?

Yes, results from the query editor can be copied or downloaded as CSV or JSON.

About the SQLite Database Viewer & Query Runner

Drop in a SQLite database file and inspect it entirely client-side: browse tables with row counts, view column schemas, page through data, and run arbitrary SQL queries with results exportable as CSV or JSON. Powered by sql.js (SQLite compiled to WebAssembly) — nothing is uploaded, and changes are never written back to the original file.

SELECT name FROM sqlite_master WHERE type='table';
