About MDB
Microsoft Access keeps a whole database in one file: its tables and the relationships between them, with its queries, forms, reports and code. Up to Access 2003 that file is an MDB, written by the Jet engine, and an MDE is one whose code was compiled and taken out. Access 2007 brought ACCDB, yet MDB files still turn up everywhere, from old business apps to public data downloads.
Inside, the data sits in pages of 2 KB in Access 97 and 4 KB from Access 2000 on, which keeps text as UTF-16, often compressed. Pictures and documents are kept as OLE objects, wrapped in the headers of the program that made them. A password on an MDB only keeps Access from opening it: the data inside is never locked with it.
Filepeek reads the file with its own copy of mdb-reader, a page at a time, and opens it as a folder of its tables, each with its columns in Access types, its primary key, its indexes and its rows counted. A relationship leads from a row to the one it points at, an OLE object opens as the file inside it, and Search looks in every table. Linked tables show where they point, and the queries, forms and reports are counted.

No browser opens an MDB file: they download it, and Access runs only on Windows. Filepeek opens it as a folder of tables in Chrome, Edge, Firefox and Safari.

Questions
How do I open an MDB file without Access?
Drop it on this page or choose Peek an MDB. Its tables show as a folder in the file list, each with its rows counted, and the one you pick opens as a grid, on a Mac, a phone or any computer.
Can it open an MDB with a password?
Yes, without asking for it. An MDB's password only keeps Access from opening the file, and its data can be read without it. The file's details say a password is set.
What happens to OLE objects?
A cell with an OLE object shows the file inside it, like a picture or a document, and the cell's card opens that file in its own viewer.
Can I save the tables as Excel or CSV?
Export saves a table as CSV, Excel, JSON, Parquet or SQL, with every row or only the rows you sorted and filtered. The same menu saves every table at once: as a ZIP of CSVs, one Excel workbook with a sheet for each table, a SQLite database or a SQL dump.
Is my file uploaded?
No. The database opens inside your browser and never leaves your device.
