Introduction

Paperless-ngx is a powerful document management system that transforms your homelab into a paperless office. Built as a fork of the original Paperless project, Paperless-ngx offers advanced features like machine learning-powered document classification, comprehensive OCR capabilities, and sophisticated workflow automation. With over 15,000 GitHub stars and active development, it has become the de facto standard for self-hosted document management.

Why Choose Paperless-ngx?

Complete Document Control

Every document you scan remains on your infrastructure. Unlike cloud services like Evernote or Dropbox Paper that monetize your data, Paperless-ngx keeps everything local. Your tax returns, medical records, and personal documents never leave your control.

Intelligent OCR and Search

Paperless-ngx uses Tesseract OCR to extract text from scanned documents, making every document fully searchable. Whether it’s a utility bill from 2019 or a receipt from last week, find it instantly with natural language search.

Zero Recurring Costs

Cloud document management services charge $10-20/month for storage and OCR processing. A typical homelab setup costs $300-500 one-time, breaking even in less than 2 years while providing unlimited storage and processing.

Production-Grade Features

  • Automatic document classification with machine learning
  • Full-text OCR in 100+ languages
  • Advanced tagging and custom metadata
  • Email import and monitoring
  • Mobile scanning apps (iOS and Android)
  • Workflow automation with webhooks
  • Multi-user support with permissions
  • Automatic duplicate detection

    networks:
      - paperless

  # Main Paperless-ngx application
  webserver:
    image: ghcr.io/paperless-ngx/paperless-ngx:latest
    container_name: paperless-app
    restart: unless-stopped
    depends_on:
      - db
      - broker
    ports:
      - "8000:8000"
    volumes:
      - data:/usr/src/paperless/data
      - media:/usr/src/paperless/media
      - ./export:/usr/src/paperless/export
      - ./consume:/usr/src/paperless/consume
    env_file: .env
    environment:
      PAPERLESS_REDIS: redis://broker:6379
      PAPERLESS_DBHOST: db
      PAPERLESS_TIKA_ENABLED: 1
      PAPERLESS_TIKA_GOTENBERG_ENDPOINT: http://gotenberg:3000
      PAPERLESS_TIKA_ENDPOINT: http://tika:9998
    networks:
      - paperless
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8000"]
      interval: 30s
      timeout: 10s
      retries: 5

  # Gotenberg for PDF generation
  gotenberg:
    image: docker.io/gotenberg/gotenberg:8
    container_name: paperless-gotenberg
    restart: unless-stopped
    command:
      - "gotenberg"
      - "--chromium-disable-javascript=true"
      - "--chromium-allow-list=file:///tmp/.*"
    networks:
      - paperless

  # Tika for advanced OCR
  tika:
    image: docker.io/apache/tika:latest
    container_name: paperless-tika
    restart: unless-stopped
    networks:
      - paperless

volumes:
  data:

  redisdata:

networks:
  paperless:
    driver: bridge

Step 3: Create Directory Structure

# Create local directories
mkdir -p consume export

# Set proper permissions
chmod 755 consume export

# Verify structure
ls -la

Step 4: Deploy the Stack

# Pull all images (this may take 5-10 minutes)
docker compose pull

# Start all services
docker compose up -d

# Monitor startup (wait 2-3 minutes for initialization)
docker compose logs -f

# Press Ctrl+C to exit log view

# Verify all containers are running
docker compose ps

Expected output shows 5 services running:

  • paperless-app - Main application
  • paperless-db - PostgreSQL database
  • paperless-redis - Task queue
  • paperless-gotenberg - PDF processing
  • paperless-tika - OCR engine

Step 5: Initial Web Interface Setup

Navigate to http://YOUR-SERVER-IP:8000 in your browser.

  1. Log in with credentials from .env:

    • Username: admin
    • Password: ChangeThisPassword123 (or your custom password)
  2. Complete initial setup wizard:

    • Set display preferences
    • Configure default storage paths
    • Set up email (optional)
  3. Verify OCR is working:

    • Upload a test scanned document
    • Wait 30-60 seconds for processing
    • Search for text from the document

Step 6: Configure Reverse Proxy (Production Setup)

For HTTPS access, configure a reverse proxy. Here’s an example using Nginx Proxy Manager:

Using Nginx Proxy Manager:

1. Add Proxy Host
2. Domain: paperless.yourdomain.com
3. Forward Hostname: paperless-app
4. Forward Port: 8000
5. Enable WebSocket Support
6. Request SSL Certificate
7. Save

Manual Nginx configuration:

server {
    listen 443 ssl http2;
    server_name paperless.yourdomain.com;

    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;

    client_max_body_size 100M;

    location / {
        proxy_pass http://localhost:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 300s;
    }
}

Document Ingestion Methods

Method 1: Web Upload

The simplest method for occasional documents:

1. Click "Upload" in top menu
2. Drag and drop files or click to browse
3. Optional: Set tags, correspondent, document type before upload
4. Click "Upload"
5. Documents process in background (30-120 seconds per document)

Supported formats:

  • PDF (most common)
  • Images: JPEG, PNG, TIFF, WEBP
  • Office: DOCX, XLSX, PPTX (converted to PDF)
  • Plain text: TXT, MD
  • Email: EML, MSG

Method 2: Consume Directory (Watch Folder)

Automatic processing of documents placed in a folder:

# Copy documents to consume folder
cp ~/Downloads/invoice.pdf ~/paperless-ngx/consume/

# Paperless automatically:
# 1. Detects new file within 10 seconds
# 2. Processes OCR
# 3. Moves to archive
# 4. Deletes original from consume folder

Advanced naming convention for automatic tagging:

Format: [date]_[correspondent]_[title]__tag1,tag2.pdf

Examples:
20250115_UtilityCompany_Electric-Bill-Jan__bills,utilities.pdf
  → Date: 2025-01-15
  → Correspondent: Utility Company
  → Title: Electric Bill Jan
  → Tags: bills, utilities

2024_AcmeCorp_Employment-Contract__legal,important.pdf
  → Year: 2024 (exact date will be extracted from document)
  → Correspondent: Acme Corp
  → Tags: legal, important

Method 3: Mobile Scanning

  → Tags: bills, utilities
  → Title: Electric bill

Subject: [correspondent:Acme Corp] [tag:receipts] Purchase receipt
  → Correspondent: Acme Corp
  → Tag: receipts
  → Title: Purchase receipt

Method 5: Bulk Import

For migrating existing document archives:

# Copy all documents to consume folder
cp -r ~/Documents/Archive/* ~/paperless-ngx/consume/

# Paperless processes them sequentially
# Monitor progress in web interface:
# Dashboard → Tasks → Document Processing

# Check logs
docker compose logs -f webserver | grep -i "processing"

Performance:

  • 10-20 documents/minute on 4-core system
  • 5-10 documents/minute on 2-core system
  • Add PAPERLESS_TASK_WORKERS=4 to .env for parallel processing

Tagging, Workflows, and Automation

Tagging Strategy

Hierarchical Tag System:

Personal/
├─ Finance/
│  ├─ Taxes
│  ├─ Bank Statements
│  └─ Receipts
├─ Medical/
│  ├─ Insurance
│  ├─ Prescriptions
│  └─ Lab Results
└─ Legal/
   ├─ Contracts
   ├─ Property
   └─ Identity

Work/
├─ Projects
├─ HR Documents
├─ Invoices
└─ Contracts

Creating tags via web interface:

1. Settings → Tags → Add Tag
2. Name: "Finance"
3. Color: #2196F3 (blue)
4. Match: "invoice|bill|statement" (regex)
5. Matching Algorithm: Auto
6. Save

Automatic tag assignment:

Tags can be auto-assigned based on document content:

Tag: "Utilities"
Match: "electric|water|gas|internet|phone"
Assignment: Auto

Tag: "Medical"
Match: "prescription|doctor|hospital|clinic"
Assignment: Auto

Tag: "Receipts"
Match: "receipt|purchase|paid"
Assignment: Auto

Document Types

Document types categorize documents for better organization:

Examples:
- Invoice
- Receipt
- Contract
- Letter
- Form
- Statement
- Report
- Certificate

Creating document type:

1. Settings → Document Types → Add
2. Name: "Invoice"
3. Match: "invoice|bill"
4. Matching Algorithm: Auto
5. Save

Correspondents

Track who sent or received documents:

Examples:

- Vendor Names

Auto-detection based on document content:

Correspondent: "Acme Corporation"
Match: "acme|acme corp"
Matching Algorithm: Auto

Workflow Automation with Webhooks

Enable webhooks in .env:

PAPERLESS_WEBHOOKS_ENABLED=true
PAPERLESS_WEBHOOK_URL=http://n8n:5678/webhook/paperless

Example webhook payload:

{
  "event": "document_added",
  "document": {
    "id": 123,
    "title": "Electric Bill - January 2025",
    "correspondent": "Utility Company",
    "document_type": "Bill",
    "created": "2025-01-15T10:30:00Z",
    "tags": ["bills", "utilities"],
    "content": "Full OCR text here..."
  }
}

Automation examples:

  1. Bill payment reminder:

    • Webhook triggers when bill is tagged
    • Extract due date from content
    • Create calendar reminder
    • Send notification
  2. Backup to cloud:

    • Document added → webhook
    • Upload to encrypted cloud storage
    • Log to audit trail
  3. Share with accountant:

    • Tax document detected
    • Auto-forward to accountant’s secure portal
    • Add to year-end tax folder
