Is my SQLite database file uploaded to a server?

No. The SQLite engine runs entirely within your browser via WebAssembly (sql.js). Database files are read into local memory and never transmitted over the internet.

Can I run arbitrary SQL queries including JOINs and aggregations?

Yes. The WebAssembly SQLite engine supports full standard SQLite SQL syntax including complex joins, subqueries, window functions, and aggregations.

Frequently Asked Questions

Can this tool corrupt or overwrite my original database file?

No. The file is loaded into memory as a read-only buffer. Any modifications made via SQL commands remain purely in volatile browser RAM and do not alter the file on your disk.

What SQLite versions are supported?

The query engine is compiled directly from SQLite 3.x official C sources via Emscripten WebAssembly, providing 100% compliance with standard SQLite features.
