Is my SQLite database uploaded to any server?

No. Your SQLite database file is processed entirely inside your browser using sql.js and WebAssembly. Your data never leaves your device.

Can I export query results?

Yes. Query results can be downloaded as CSV or JSON files with a single click.

sql.js is the SQLite database engine compiled to WebAssembly using Emscripten. It allows SQLite databases to run directly inside web browsers.

Does this tool support large databases?

Yes. Files up to 100MB are supported. Performance depends on your device memory and browser capabilities.

Can I modify the database file permanently?

You can run write queries in memory, but changes are not saved back to the original database file in the current version.

Why use an online SQLite browser instead of desktop software?

An online SQLite browser lets you inspect databases instantly with no installation required. It is ideal for quick debugging, learning SQL, mobile app database inspection and exporting data.

Can I inspect Android or iPhone app databases?

Yes. Many Android and iOS apps use SQLite for local storage. Exported app database files can be opened and inspected with this tool.

What Is an SQLite Database Browser?

An SQLite database browser is a tool that lets you open, inspect and query SQLite database files without installing any software. Traditional SQLite browsers like DB Browser for SQLite or DBeaver are desktop applications — this tool runs entirely in your browser using sql.js, a WebAssembly port of the official SQLite library.

SQLite is the most widely deployed database engine in the world. It is used in Android and iOS apps, browsers, desktop applications, Electron apps, Python scripts, and thousands of developer tools. The database is stored as a single file with a .db, .sqlite or .sqlite3 extension. When you need to inspect what is inside one of those files quickly, without installing a desktop app or spinning up a server, this browser is the fastest path.

Common Use Cases

📱

Inspect Mobile App Data

Android and iOS apps store local data in SQLite. Exported database files can be opened here to see what data your app is storing.

🐍

Debug Python Scripts

Python's sqlite3 module is part of the standard library. Quickly inspect the .db files your scripts create without writing extra SELECT statements.

⚡

Browse Electron App Databases

Many Electron apps like Slack, VS Code extensions and others use SQLite for local storage. Inspect those databases here.

📊

Export Data for Analysis

Run SELECT queries and export results as CSV for import into Excel, Google Sheets or any data analysis tool.

✅

Verify Database Migrations

After running a migration, open the database here to confirm the schema looks correct before deploying.

How It Works: WebAssembly SQLite

This tool uses sql.js — the official SQLite library compiled to WebAssembly using Emscripten. When you upload a database file, it is read into browser memory as a byte array and passed to the WebAssembly SQLite engine. The engine processes your SQL queries entirely within the browser sandbox. No network request is made. Your data never touches a server.

The result is full SQLite 3 compatibility — PRAGMA statements, JSON functions, window functions, full-text search and everything else SQLite supports — running directly in your browser tab.

Frequently Asked Questions

Everything about the SQLite Database Browser

Do I need to sign up or log in to use this tool?

No. All QuickTextTools are completely free to use online with no login, signup, or account required.

Is my database file sent to any server?

No. Your database file is opened entirely in your browser using sql.js — a WebAssembly port of SQLite. The file never leaves your device. No data is uploaded, stored or transmitted.

What SQLite file formats are supported?

The tool supports all standard SQLite database file extensions: .db, .sqlite, .sqlite3, .db3, .s3db and .sl3. Any valid SQLite 3 database file should open correctly.

What is the maximum file size?

The browser can handle files up to 100MB. For larger databases, the file is loaded into browser memory so performance depends on your device's available RAM.

Can I run write queries like INSERT, UPDATE or DELETE?

Yes. The query editor supports all SQL — SELECT, INSERT, UPDATE, DELETE, CREATE, DROP and PRAGMA statements. However, changes are only in memory and are not saved back to the original file.

Can I download the modified database after running write queries?

Currently the tool focuses on browsing and querying. Export options are available for query results as CSV and JSON. Downloading a modified .db file is not supported in the current version.

What SQL dialect does this tool use?

The tool uses sql.js which is a WebAssembly build of SQLite 3. It supports the full SQLite SQL dialect including PRAGMA statements, JSON functions, window functions and all standard SQLite features.

Why does my query run slowly on large tables?

The database is loaded entirely into browser memory. Queries without WHERE clauses on large tables scan every row, which can be slow. Use LIMIT and WHERE clauses to constrain result sets. Adding indexes via CREATE INDEX can also improve performance.
