Input file

Our API uses a *.MDB file as input. These MDB files are typically created by Microsoft Access up to version 2003. More recent Microsoft Access versions create ACCDB files, check out our ACCDB converter.

Max file size for web uploads: 50 GB

Output file

The API will return a ZIP archive that contains a .SQL file. This .SQL is a PostgreSQL dump file and can be restored into your PostgreSQL installation.

How long does it take?

The conversion process takes between 15 seconds and multiple minutes. It depends on the size of the database.
