Extract text from database files (DB)
To convert DB databases to another format, you need DB Browser for SQLite or other Database software.
To convert other file formats to the "Relational Database File" file type, you need software like DB Browser for SQLite or a similar tool.
The .DB file extension represents a generic database file format, most commonly implemented as an SQLite 3 relational database. These files store structured data in a highly compressed binary format, containing tables, views, indexes, and triggers. They are widely used as embedded data stores in mobile apps (like ColorOS Notes or Skype history), open-source projects like LiteDB, and system-level caches (such as Windows thumbs.db or macOS system data stores). To interact with these files natively, developers typically use DB Browser for SQLite or DBeaver.
The primary disadvantage of the .DB format is its opacity. Because it is a compiled binary file, opening a .DB file in a standard text editor will only display garbled text. Furthermore, a single .DB file often contains multiple relational tables, making it impossible to directly open in standard spreadsheet software like Excel without specialized querying tools. System-generated .DB files are also notorious for being locked by background OS processes, preventing users from moving or deleting them easily.
To make the data readable and portable, you must extract it. For data analysis and spreadsheet editing, convert your tables to CSV or XLSX. If you are building web applications or APIs, convert the data to JSON. For archiving or migrating to another database engine (like MySQL or PostgreSQL), convert the file to a plain text SQL dump.

Convert.Guru analyzes your DB file, detects the exact format, and lets you read the text inside.
Users also converted DATABASE, THUMBS, THUMB, SQLITE, DB-SHM, DB-WAL, DB-JOURNAL, CRYPT14, SQLITE3, JPG, TXT, ZIP and SQL files.
If you want to convert DB file to CSV, DBM, DBA, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB or MYD, you can use DB Browser for SQLite or similar software from the "Relational Database Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB3, SQLITE or FRM files to DB, try DB Browser for SQLite or another comparable tool in the "Relational Database Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DB converter.
