🚀 Getting Started

You can run BentoPDF locally for development or personal use.

Prerequisites

• Node.js (v18 or higher recommended)
• npm (or yarn/pnpm)
• Docker & Docker Compose (for containerized setup)

🚀 Quick Start

Run BentoPDF instantly from GitHub Container Registry (Recommended):

docker run -p 3000:8080 ghcr.io/alam00000/bentopdf:latest

Open your browser at: http://localhost:3000

Alternative: Using Docker Hub or Podman

Docker Hub:

docker run -p 3000:8080 bentopdfteam/bentopdf:latest

Podman (GHCR):

podman run -p 3000:8080 ghcr.io/alam00000/bentopdf:latest

Podman (Docker Hub):

podman run -p 3000:8080 docker.io/bentopdfteam/bentopdf:latest

Note: All docker commands in this documentation work with Podman by replacing docker with podman.

Static Hosting using Netlify, Vercel, and GitHub Pages

It is very straightforward to host your own instance of BentoPDF using a static web page hosting service. Plus, services such as Netlify, Vercel, and GitHub Pages all offer a free tier for getting started. See Static Hosting for details.

🏠 Self-Hosting Locally

Since BentoPDF is fully client-side, all processing happens in the user's browser and no server-side processing is required. This means you can host BentoPDF as simple static files on any web server or hosting platform.

Download from Releases (Recommended):

The easiest way to self-host is to download the pre-built distribution file from our GitHub releases. Each release includes a dist-{version}.zip file that contains all necessary files for self-hosting.

1. Go to BentoPDF Releases
2. Download the latest dist-{version}.zip file
3. Extract the zip file
4. Serve the extracted folder with your preferred web server

Serve the extracted folder (requires Node.js):

# Navigate to the extracted folder
cd dist-1.7.3  # Replace with your version

# Start a local server
npx http-server -c-1

The website will be accessible at: http://localhost:8080/

Note: The -c-1 flag disables caching for development.

Build from Source (Advanced):

If you prefer to build from source:

# Clone the repository
git clone https://github.com/alam00000/bentopdf.git
cd bentopdf

# Install dependencies
npm install

# Build the project
npm run build

# Package the distribution for hosting (optional)
npm run package

# Preview the build locally
npm run preview

# The website will be accessible at: http://localhost:4173/

Compression Modes:

BentoPDF supports different compression modes for optimized builds:

# Gzip only (smallest Docker image size)
npm run build:gzip
docker build --build-arg COMPRESSION_MODE=g -t bentopdf:gzip .

# Brotli only (best compression ratio)
npm run build:brotli
docker build --build-arg COMPRESSION_MODE=b -t bentopdf:brotli .

# No compression (fastest build time)
npm run build:original
docker build --build-arg COMPRESSION_MODE=o -t bentopdf:original .

# All formats (default, maximum browser compatibility)
npm run build:all
docker build --build-arg COMPRESSION_MODE=all -t bentopdf:all .

Mode	Files Kept	Use Case
g	.gz only	Standard nginx or minimal size
b	.br only	Modern CDN with Brotli support
o	originals	Development or custom compression
all	all formats	Maximum compatibility (default)

CDN Optimization:

BentoPDF can use jsDelivr CDN to serve large WASM files (LibreOffice, Ghostscript, PyMuPDF) for improved performance and reduced bandwidth costs:

# Production build with CDN (Recommended)
VITE_USE_CDN=true npm run build

# Standard build with local files only
npm run build

How it works:

• When VITE_USE_CDN=true: Browser loads WASM files from jsDelivr CDN (fast, global delivery)
• Local files are always included as automatic fallback
• If CDN fails then it falls back to local files

Subdirectory Hosting:

BentoPDF can also be hosted from a subdirectory (e.g., example.com/tools/bentopdf/):

# Example:
# 1. Build the app with the specific BASE_URL. BASE_URL must have a trailing and leading slash. The BASE_URL can be any url of your choice. Here we are using /tools/bentopdf/ as an example.

BASE_URL=/tools/bentopdf/ npm run build

# 2. Create the nested directory structure inside serve-test (or any folder of your choice for local testing. In case of production, create the nested directory structure inside the root directory)
mkdir -p serve-test/tools/bentopdf

# 3. Copy all files from the 'dist' folder into that nested directory
cp -r dist/* serve-test/tools/bentopdf/

# 4. Serve the 'serve-test' folder
npx serve serve-test

The website can be accessible at: http://localhost:3000/tools/bentopdf/

The npm run package command creates a dist-{version}.zip file that you can use for self-hosting.

Docker Subdirectory Deployment:

BentoPDF's Docker image also supports the BASE_URL build argument for subdirectory deployments:

# Build for subdirectory deployment
docker build --build-arg BASE_URL=/bentopdf/ -t bentopdf .

# Run the container
docker run -p 3000:8080 bentopdf

# The app will be accessible at http://localhost:3000/bentopdf/

Combined with Simple Mode:

# Build with both BASE_URL and SIMPLE_MODE
docker build \
  --build-arg BASE_URL=/tools/pdf/ \
  --build-arg SIMPLE_MODE=true \
  -t bentopdf-simple .

docker run -p 3000:8080 bentopdf-simple

Important:

• Always include trailing slashes in BASE_URL (e.g., /bentopdf/ not /bentopdf)
• The default value is / for root deployment

🚀 Run with Docker Compose / Podman Compose (Recommended)

For a more robust setup with auto-restart capabilities:

1. Download the repo and create a docker-compose.yml file or use the one given in repo:

services:
  bentopdf:
    image: ghcr.io/alam00000/bentopdf:latest # Recommended
    # image: bentopdfteam/bentopdf:latest     # Alternative: Docker Hub
    container_name: bentopdf
    ports:
      - '3000:8080'
    restart: unless-stopped

2. Start the application:

# Docker Compose
docker-compose up -d

# Podman Compose
podman-compose up -d

The application will be available at http://localhost:3000.

🐧 Podman Quadlet (Systemd Integration)

For Linux production deployments, you can run BentoPDF as a systemd service using Podman Quadlet.

Create ~/.config/containers/systemd/bentopdf.container:

[Unit]
Description=BentoPDF - Privacy-first PDF toolkit
After=network-online.target

[Container]
Image=ghcr.io/alam00000/bentopdf:latest
ContainerName=bentopdf
PublishPort=3000:8080
AutoUpdate=registry

[Service]
Restart=always

[Install]
WantedBy=default.target

Then enable and start:

systemctl --user daemon-reload
systemctl --user enable --now bentopdf

For detailed Quadlet configuration, see Self-Hosting Docker Guide.

🏢 Simple Mode for Internal Use

For organizations that want a clean, distraction-free interface focused solely on PDF tools, BentoPDF supports a Simple Mode that hides all branding and marketing content.

What Simple Mode does:

• Hides navigation, hero section, features, FAQ, testimonials, and footer
• Shows only the essential PDF tools
• Updates page title to "PDF Tools"
• Perfect for internal company tools and educational institutions

For more details, see SIMPLE_MODE.md.

🔒 Security Features

BentoPDF runs as a non-root user using nginx-unprivileged for enhanced security:

• Non-Root Execution: Container runs with minimal privileges using nginx-unprivileged
• Port 8080: Uses high port number to avoid requiring root privileges
• Security Best Practices: Follows Principle of Least Privilege

Basic Usage

docker build -t bentopdf .
docker run -p 8080:8080 bentopdf

For detailed security configuration, see SECURITY.md.

Digital Signature CORS Proxy (Required)

The Digital Signature tool uses a signing library that may need to fetch certificate chain data from certificate authority provider. Since many certificate servers don't include CORS headers, a proxy is required for this feature to work in the browser.

When is the proxy needed?

• Only when using the Digital Signature tool
• Only if your certificate requires fetching issuer certificates from external URLs
• Self-signed certificates typically don't need this

Deploying the CORS Proxy (Cloudflare Workers):

1. Navigate to the cloudflare directory:

   cd cloudflare

2. Login to Cloudflare (if not already):

   npx wrangler login

3. Deploy the worker:

   npx wrangler deploy

4. Note your worker URL (e.g., https://bentopdf-cors-proxy.your-subdomain.workers.dev)

5. Set the environment variable when building:

   VITE_CORS_PROXY_URL=https://your-worker-url.workers.dev npm run build

Production Security Features

The CORS proxy includes several security measures:

Feature	Description
URL Restrictions	Only allows certificate URLs (.crt, .cer, .pem, /certs/, /ocsp)
Private IP Blocking	Blocks requests to localhost, 10.x, 192.168.x, 172.16-31.x
File Size Limit	Rejects files larger than 10MB
Rate Limiting	60 requests per IP per minute (requires KV)
HMAC Signatures	Optional client-side signing (limited protection)

Enabling Rate Limiting (Recommended)

Rate limiting requires Cloudflare KV storage:

cd cloudflare

# Create KV namespace
npx wrangler kv namespace create "RATE_LIMIT_KV"

# Copy the returned ID and add to wrangler.toml:
# [[kv_namespaces]]
# binding = "RATE_LIMIT_KV"
# id = "YOUR_ID_HERE"

# Redeploy
npx wrangler deploy

Free tier limits: 100,000 reads/day, 1,000 writes/day (~300-500 signatures/day)

HMAC Signature Verification (Optional)

⚠️ Security Warning: Client-side secrets can be extracted from bundled JavaScript. For production deployments with sensitive requirements, use your own backend server to proxy requests instead of embedding secrets in frontend code.

BentoPDF uses client-side HMAC as a deterrent against casual abuse, but accepts this tradeoff due to its fully client-side architecture. To enable:

# Generate a secret
openssl rand -hex 32

# Set on Cloudflare Worker
npx wrangler secret put PROXY_SECRET

# Set in build environment
VITE_CORS_PROXY_SECRET=your-secret npm run build

📦 Version Management

BentoPDF supports semantic versioning with multiple container tags available:

GitHub Container Registry (Recommended):

• Latest: ghcr.io/alam00000/bentopdf:latest
• Specific Version: ghcr.io/alam00000/bentopdf:1.0.0
