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 multi user, on-prem or cloud 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 10 (64-bit) or higher with .NET Framework 4.8


- Store and manage PDF documents in a single-user or compatible, multi-user (on-prem or cloud) database where they’re indexed to provide full-text search functionality.

- Upload PDF documents individually or in bulk. In addition, Upload Profile folders can be setup to allow for integration and automation.

- Apply a category/tax year to selected documents and when PDF documents are uploaded.

- Set the flag state on a selected document and when PDF documents are uploaded to mark for follow-up.

- Add notes to a selected document that can include the date, time, and user account name. All notes can be edited and are indexed by the database.

- Find documents by Search Term, Selections (Author/Subject/Category/Tax Year), or Date Added. In addition, flagged documents or all documents can be listed.

- With PDFKeeper, the following functions can be performed on a selected document: PDF viewing with the bundled or default viewer; PDF bursting; flag document state management; notes viewing and editing; keywords, PDF preview, PDF text, and search term snippets (when applicable) are also displayed for viewing.

- Export selected PDF documents with their category, tax year, notes, and flag state from the database for easy importing.
