How to open a .DB3 file online
Three steps, a few seconds.
01
Open your .DB3 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 .DB3 file?
The most widely deployed database engine in the world.
A .db3 file is a SQLite 3 database, the same format as .sqlite and .db but with a different extension. Open it for free with DB Browser for SQLite on Windows, macOS, or Linux. The file holds structured data (tables, indexes, rows), not a document, so you browse it rather than read it like a text file.

Frequently asked questions
Is my .DB3 file uploaded anywhere?
No. The SQLite engine (compiled to WebAssembly) is downloaded once to your browser and opens your .DB3 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.
