PDFKeeper is free, open source software that provides a storage and management solution for PDF documents.
This software requires a relational database for document storage. It can be implemented for single user use with the builtin, local SQLite database or in a client-server environment using a compatible database. Please note, future versions might extend support for other database management systems. You can request this by posting an issue on its GitHub page available here.
Note: PDFKeeper requires Windows (64 bit) with .NET Framework 4.8
- Store and manage PDF documents in a local or compatible, client-server relational database where they’re indexed to provide full-text search functionality.
- Upload PDF documents individually or in bulk. In addition, configured folders can be setup to allow for integration and automation.
- Apply a category and/or tax year to selected document records and when PDF documents are uploaded.
- Set the flag state on a selected document record and when PDF documents are uploaded to mark for follow-up.
- Add notes to a selected document record that can include the date, time, and user account name. All notes can be edited and are indexed by the database.
- Search for document records by Text, Selections (Author/Subject/Category/Tax Year), or Date Added. In addition, the user can list document records that are flagged or all document records in the database.
- With PDFKeeper, the following functions can be performed on a selected document record: PDF document viewing with the bundled or default viewer; flag document state management; notes viewing and editing; keywords, PDF preview, and PDF text are also displayed for viewing.
- Export selected PDF documents with their category, tax year, notes, and flag state from the database for easy importing.
