Convert DB files online for free
The converter easily converts your DB file to various formats - free and online. No Excel or extra software needed.
The converter also works in reverse, so you can convert other Database formats to DB with high quality output.
A .DB file is most frequently a generic database file, with the vast majority being SQLite databases. These are self-contained, serverless SQL database engines used by thousands of applications - from mobile apps (Android/iOS) to web browsers (Chrome/Firefox) and desktop software - to store local data. A secondary but common variation is the Thumbs.db file, a hidden system cache generated by Microsoft Windows to speed up thumbnail loading in Explorer folders.
While SQLite .DB files are highly efficient for software, they pose significant challenges for end-users: they are binary files that cannot be opened in text editors like Notepad or spreadsheet tools like Excel directly. To view or manipulate the data, users typically require specialized tools like DB Browser for SQLite or knowledge of SQL command-line interfaces. For Thumbs.db files, the challenge is proprietary encoding; they are often locked by the operating system and require dedicated extraction tools to recover the images inside.
For most users, the practical solution is converting the .DB file into a human-readable format. For data analysis and reporting, converting SQLite files to CSV, XLSX (Excel), or JSON allows for immediate use in standard office software. For archiving or migration, converting to a SQL dump preserves the schema and data structure. System cache files like Thumbs.db are best converted to standard image formats like JPG or PNG to recover the thumbnail content.
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 SQLite or similar software from the "Structured Data 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 SQLite or another comparable tool in the "Structured Data 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.
