Paperless-ngx

Documents

Turn paper and PDFs into a searchable document archive.

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.

  • 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.
