Is SQLite Browser Safe?

Yes — the SQLite Browser is completely safe. It runs entirely in your browser and your data never touches any server.

Your Files Stay Local

When you open a SQLite file, it's read into your browser's memory using the FileReader API. The file is never uploaded anywhere. All SQL queries execute locally via the sql.js WebAssembly engine.

No Credentials Needed

There's no server to connect to, no passwords to enter, and no network requests involved in querying your data.

Data Is Ephemeral

Everything is stored in memory. When you close or refresh the tab, all data is gone. Only your query history persists (stored in IndexedDB).

Works Offline

Once the page is loaded, the SQLite engine runs independently. You can disconnect from the internet and continue working with your database.

Best Practices

• Export your database before closing the tab if you've made changes
• For very large databases, make sure your device has enough available RAM
• Keep a backup of your original file before making modifications
