What is a DB file?
A .DB file is a generic database file used to store structured data. Many different applications use the .DB extension. The most common format is a SQLite 3 database file. Developers use SQLite to store data locally in mobile applications, web browsers, and desktop software.
Common DB formats
Because .DB is a generic extension, the internal format varies. Common uses include:
- SQLite Databases: Used by Mozilla Firefox, Skype, and macOS system tools.
- Windows Cache Files: Microsoft Windows generates `thumbs.db` and `iconcache.db` files to store thumbnail images and folder icons.
- Embedded Databases: Projects like LiteDB and the H2 Database Engine use .DB files for local storage.
- Game and App Data: Software like the X-Ray Engine by GSC Game World and Android privacy safes use this extension to store local assets.
How to open DB files?
If your .DB file is a SQLite database, you can open it with DB Browser for SQLite or the official SQLite command-line tool. If it is a Windows `thumbs.db` file, you usually do not need to open it manually, as Windows File Explorer manages it automatically. Because the extension has multiple possible meanings, it is often difficult to know which software to use.
viewer.online/db analyzes .DB files to identify their exact format and creator software. It shows which programs can open the file and usually previews it directly in your browser. If you need to convert your database data, we recommend using convert.guru to change it into .CSV, .JSON, or .SQL formats.
Summary
viewer.online/db directly opens and previews .DB files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
