A .db file usually holds a SQLite database, the engine built into nearly every device. SQLite’s developers have publicly pledged to keep the file format supported and cross-compatible through to the year 2050. SQLite, the engine behind most .db files, was placed in the public domain by its creator D. Richard Hipp. Hipp designed SQLite in 2000 while on a US Navy contract, aiming for a database that needs no separate server.

How do I open a .DB file?

Drop a .DB file onto Analyser at https://analyser.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Open SQLite databases (.sqlite/.db/.sqlite3) and read their full schema in-browser - every table with its columns and row counts, views, indexes, triggers, the CREATE-statement DDL, and a sample of the largest table. Reads the WAL-mode sidecars too: the Write-Ahead Log (-wal) - page size, salts, frame and committed-transaction counts, and the pages it changed - and the shared-memory index (-shm) - valid frame count, database size and checkpoint progress. (.sql dumps are listed under Developer / data.) Microsoft Access (MDB, ACCDB) now opens in a full table viewer - see Access database above. Concordance .dcb databases from the LexisNexis litigation review suite are identified from their bytes, and told apart from the other formats that reuse the same extension (compiled game data, speech-recognition dictionaries).

Can I open a .DB file online for free?

Yes. Analyser is a free online .DB identifier that runs entirely in your browser - your .DB file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .DB file?

A .db file usually holds a SQLite database, the engine built into nearly every device.

Did you know: SQLite’s developers have publicly pledged to keep the file format supported and cross-compatible through to the year 2050.
SQLite, the engine behind most .db files, was placed in the public domain by its creator D. Richard Hipp.
Hipp designed SQLite in 2000 while on a US Navy contract, aiming for a database that needs no separate server.
What Analyser reads: Open SQLite databases (.sqlite/.db/.sqlite3) and read their full schema in-browser - every table with its columns and row counts, views, indexes, triggers, the CREATE-statement DDL, and a sample of the largest table. Reads the WAL-mode sidecars too: the Write-Ahead Log (-wal) - page size, salts, frame and committed-transaction counts, and the pages it changed - and the shared-memory index (-shm) - valid frame count, database size and checkpoint progress. (.sql dumps are listed under Developer / data.) Microsoft Access (MDB, ACCDB) now opens in a full table viewer - see Access database above. Concordance .dcb databases from the LexisNexis litigation review suite are identified from their bytes, and told apart from the other formats that reuse the same extension (compiled game data, speech-recognition dictionaries).
Depth of analysis: .DB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .DB file: Drag a .DB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
