How to open a .DB file online
Three steps, a few seconds.
01
Open your .DB file
Drop the file on the box or click to choose it. It opens.
02
Browse the tables
Pick a table to page through its rows, sort any column or filter by text. The Structure tab shows its columns, keys and indexes.
03
Run a query
Write any SELECT or JOIN and export the result as CSV or JSON. Changes live in memory until you download a copy.
What is a .DB file?
The most widely deployed database engine in the world.
A .db file is almost always a SQLite database, the single-file format that Android apps, browsers, and desktop programs use to store their data. Open it with the free DB Browser for SQLite (Windows/macOS/Linux) or with the sqlite3 command line. If the file starts with anything other than "SQLite format 3" it is not a SQLite database; it could be a Windows Thumbs.db cache or a proprietary app format instead.

Frequently asked questions
Is my .DB file uploaded anywhere?
No. The SQLite engine (compiled to WebAssembly) is downloaded once to your browser and opens your .DB file locally. Your data never reaches FileExtension.org.
Can I change data with UPDATE or DELETE?
Yes - any SQL works, but changes only live in memory. Use Download database to save a modified copy; your original file is never touched.
Why does my .db file say it isn't SQLite?
Many programs use the .db extension for their own formats (for example Windows Thumbs.db or Paradox tables). The viewer checks the file's signature and tells you what it really is.
Can it open encrypted databases?
Not yet. Encrypted databases (SQLCipher, used by some messengers) look like random data without the key, so they can't be read.
What about the -wal and -shm files next to my database?
They hold recent changes that haven't been merged into the main file yet. Open the main database file; very recent changes stored only in the -wal file won't be visible.
