What is it?

Papermerge OSS is a self-hosted document management system built for scanned documents and digital archives. It runs OCR on uploaded scans, indexes the extracted text, and makes it searchable, so long-term paper records can be stored and found without manual filing.

The web UI follows the layout of a desktop file browser, with a dual-panel view, drag and drop, hierarchical folders, colored tags and document types. Documents support versioning, page-level operations such as reordering, cutting, moving and extracting pages, and custom metadata fields per document type. Multiple users and groups can share documents and folders.

It accepts PDF, TIFF, JPEG and PNG files and exposes an OpenAPI-compliant REST API. The project ships as a Docker image for quick deployment and includes a development setup with PostgreSQL, a backend and frontend, and CLI commands for tasks such as building the search index.
