What is Paperless-ngx?

Paperless-ngx replaces piles of paper and scattered PDFs with one archive on your own server. Documents are read, indexed and filed as they arrive, so finding a contract or invoice becomes a search rather than a hunt.

Paperless-ngx is a document management system that turns physical and digital documents into a searchable online archive. It runs OCR in 100+ languages, auto-tags documents with machine learning, imports from email, stores PDF/A copies alongside the originals, and keeps everything on your own server.

Core capabilities

  • OCR scanned documents in more than 100 languages so every page is searchable.
  • Auto-assign tags, correspondents and document types with machine learning.
  • Import from email accounts and control access with per-document permissions.

Capture, OCR and long-term storage

Paperless-ngx performs OCR with the open-source Tesseract engine in more than 100 languages, adding searchable text even to image-only scans. It handles PDFs, images, plain text and Office documents, and saves PDF/A copies for long-term storage alongside the unaltered originals.

  • PDF/A
  • Office documents

Organise and find documents

Machine learning adds tags, correspondents and document types automatically. Full-text search offers auto-completion, relevance ranking, highlighting and similar-document results, and the web app adds dashboards, saved views, custom fields and bulk editing.

  • Full-text search
  • Custom fields

Private by default, shareable on demand

Documents stay on your own server unless you choose to share them. A multi-user permission system works globally or per document, email accounts can be processed with rules, and optional AI features for suggestions and document chat are disabled by default.

  • Email import
