Is my data safe? Does DBTool upload my databases to a server?

Absolutely safe. DBTool processes all databases locally in your browser using WebAssembly (sql.js). Your database files never leave your device. There are no network requests, no server uploads, and no data collection. Everything happens 100% client-side in your browser.

What file formats does DBTool support?

DBTool supports SQLite databases (.db, .sqlite, .sqlite3), CSV files, TSV files, JSON (array of objects), XML files, HTML tables, SQL dump files, and URLs to load data directly from the web. You can also load multiple files simultaneously and convert between formats.

Can I edit my database and save the changes?

Yes! You can edit any cell by clicking on it, add new rows, delete records, and run INSERT/UPDATE/DELETE queries. When you're done editing, simply download the modified database file using the Download button. Your changes are preserved in the downloaded file.

Do I need to know SQL to use DBTool?

Not necessarily! DBTool includes a Visual Query Builder that lets you build queries without writing SQL code. Simply select your table, choose columns, add filters, and DBTool generates the SQL for you. However, if you know SQL, you can write queries directly with autocomplete support.

Can I compare two databases to find differences?

Yes! Load two or more databases, then click the Compare button. DBTool will show you tables that exist in both databases, tables unique to each database, schema differences, and row count comparisons. This is perfect for validating migrations or comparing development vs production databases.

Is DBTool free? Are there any limitations?

DBTool is completely free with no hidden costs, premium features, or subscriptions. All features are available to everyone. The only limitation is browser memory - very large databases (over 100MB) may take longer to load depending on your system resources.
