🚀 Getting Started

You can run BentoPDF locally for development or personal use.

Prerequisites

🚀 Quick Start

Run BentoPDF instantly from GitHub Container Registry (Recommended):

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

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

[!TIP]
BentoPDF ships in two builds:
> - Self-Hosted build — ghcr.io/alam00000/bentopdf-simple:latest. Every PDF tool the public site has, without the BentoPDF marketing (no hero, FAQ, testimonials, footer). Use this for internal/team/organization deployments. It is not a feature-reduced lite version.
- Commercial build — ghcr.io/alam00000/bentopdf:latest. The full marketing site, used by bentopdf.com itself and by commercial license holders running public-facing deployments. Includes hero, FAQ, testimonials, and footer.
> If in doubt: pull the Self-Hosted build.

Alternative: Using Docker Hub or Podman

Docker Hub:

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

Podman (GHCR):

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

Podman (Docker Hub):

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

[!IMPORTANT]
Office file conversion uses LibreOffice WASM, which requires SharedArrayBuffer. That means the app must be both cross-origin isolated and served from a secure context. http://localhost works for local testing, but http://192.168.x.x or other LAN IPs usually require HTTPS even if the server already sends the correct COOP/COEP headers.

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

⚙️ WASM Configuration

Advanced PDF features (PyMuPDF, Ghostscript, CoherentPDF) are pre-configured to load from jsDelivr CDN via environment variables. This means all features work out of the box — no manual setup needed.

The default URLs are set in .env.production:

VITE_WASM_PYMUPDF_URL=https://cdn.jsdelivr.net/npm/@bentopdf/[email protected]/
VITE_WASM_GS_URL=https://cdn.jsdelivr.net/npm/@bentopdf/[email protected]/assets/
VITE_WASM_CPDF_URL=https://cdn.jsdelivr.net/npm/[email protected]/dist/
VITE_TESSERACT_WORKER_URL=
VITE_TESSERACT_CORE_URL=
VITE_TESSERACT_LANG_URL=
VITE_TESSERACT_AVAILABLE_LANGUAGES=
VITE_OCR_FONT_BASE_URL=

To override via Docker build args:

docker build \
  --build-arg VITE_WASM_PYMUPDF_URL=https://your-server.com/pymupdf/ \
  --build-arg VITE_WASM_GS_URL=https://your-server.com/gs/ \
  --build-arg VITE_WASM_CPDF_URL=https://your-server.com/cpdf/ \
  --build-arg VITE_TESSERACT_WORKER_URL=https://your-server.com/ocr/worker.min.js \
  --build-arg VITE_TESSERACT_CORE_URL=https://your-server.com/ocr/core \
  --build-arg VITE_TESSERACT_LANG_URL=https://your-server.com/ocr/lang-data \
  --build-arg VITE_TESSERACT_AVAILABLE_LANGUAGES=eng,deu \
  --build-arg VITE_OCR_FONT_BASE_URL=https://your-server.com/ocr/fonts \
  -t bentopdf .

To disable a module (require manual user config via Advanced Settings), set its variable to an empty string.

For OCR, either leave all VITE_TESSERACT_* variables empty and use the default online assets, or set the worker/core/lang URLs together for self-hosted/offline OCR. If your self-hosted bundle only includes a subset such as eng,deu, also set VITE_TESSERACT_AVAILABLE_LANGUAGES=eng,deu so the UI only shows bundled languages and OCR fails with a descriptive message for unsupported ones. For fully offline searchable-PDF output, also set VITE_OCR_FONT_BASE_URL to the internal directory that serves the bundled OCR text-layer fonts.

Users can also override these defaults per-browser via Advanced Settings in the UI — user overrides take priority over the environment defaults.

[!IMPORTANT]
These URLs are baked into the JavaScript at build time. The WASM files themselves are downloaded by the user's browser at runtime — Docker does not download them during the build.

🔒 Air-Gapped / Offline Deployment

For networks with no internet access (government, healthcare, financial, etc.), you need to prepare everything on a machine with internet, then transfer the bundle into the isolated network.

Automated Script (Recommended)

The included prepare-airgap.sh script automates the entire process — downloading WASM packages, building the Docker image, exporting everything into a self-contained bundle with a setup script.

git clone https://github.com/alam00000/bentopdf.git
cd bentopdf

Show supported OCR language codes (for --ocr-languages)

bash scripts/prepare-airgap.sh --list-ocr-languages

Search OCR language codes by name or abbreviation

bash scripts/prepare-airgap.sh --search-ocr-language german

Interactive mode — prompts for all options

bash scripts/prepare-airgap.sh

Or fully automated

bash scripts/prepare-airgap.sh --wasm-base-url https://internal.example.com/wasm

This produces a bundle directory containing:

bentopdf-airgap-bundle/
  bentopdf.tar              # Docker image
  *.tgz                     # WASM packages (PyMuPDF, Ghostscript, CoherentPDF, Tesseract)
  tesseract-langdata/       # OCR traineddata files
  ocr-fonts/                # OCR text-layer font files
  setup.sh                  # Setup script for the air-gapped side
  README.md                 # Instructions

Transfer the bundle into the air-gapped network via USB, internal artifact repo, or approved method. Then run the included setup script:

cd bentopdf-airgap-bundle
bash setup.sh

The setup script loads the Docker image, extracts WASM files, and optionally starts the container.

Script options

| Flag | Description | Default | | ------------------------------ | ------------------------------------------------ | --------------------------------- | | --wasm-base-url | Where WASMs will be hosted internally | _(required, prompted if missing)_ | | --image-name | Docker image tag | bentopdf | | --output-dir | Output bundle directory | ./bentopdf-airgap-bundle | | --simple-mode | Enable Simple Mode | off | | --base-url | Subdirectory base URL (e.g. /pdf/) | / | | --language | Default UI language (e.g. fr, de) | _(none)_ | | --brand-name | Custom brand name | _(none)_ | | --brand-logo | Logo path relative to public/ | _(none)_ | | --footer-text | Custom footer text | _(none)_ | | --ocr-languages | Comma-separated OCR languages to bundle | eng | | --list-ocr-languages | Print supported OCR codes and names, then exit | off | | --search-ocr-language | Search OCR codes by name or abbreviation | off | | --dockerfile | Dockerfile to use | Dockerfile | | --skip-docker | Skip Docker build and export | off | | --skip-wasm | Skip WASM download (reuse existing .tgz files) | off |

The interactive prompt also accepts list to print the full supported Tesseract code list and search to find matches such as search german or search chi.

[!IMPORTANT]
WASM files must be served from the same origin as the BentoPDF app. Web Workers use importScripts() which cannot load scripts cross-origin. For example, if BentoPDF runs at https://internal.example.com, the WASM base URL should also be https://internal.example.com/wasm.

Manual Steps

If you prefer to do it manually without the script

Step 1: Download the WASM and OCR packages (on a machine with internet)

npm pack @bentopdf/[email protected]
npm pack @bentopdf/gs-wasm
npm pack coherentpdf
npm pack [email protected]
npm pack [email protected]
mkdir -p tesseract-langdata
curl -fsSL https://cdn.jsdelivr.net/npm/@tesseract.js-data/eng/4.0.0_best_int/eng.traineddata.gz -o tesseract-langdata/eng.traineddata.gz
mkdir -p ocr-fonts
curl -fsSL https://raw.githack.com/googlefonts/noto-fonts/main/hinted/ttf/NotoSans/NotoSans-Regular.ttf -o ocr-fonts/NotoSans-Regular.ttf

Step 2: Build the Docker image with internal URLs

git clone https://github.com/alam00000/bentopdf.git
cd bentopdf

docker build \ --build-arg VITE_WASM_PYMUPDF_URL=https://internal-server.example.com/wasm/pymupdf/ \ --build-arg VITE_WASM_GS_URL=https://internal-server.example.com/wasm/gs/ \ --build-arg VITE_WASM_CPDF_URL=https://internal-server.example.com/wasm/cpdf/ \ --build-arg VITE_TESSERACT_WORKER_URL=https://internal-server.example.com/wasm/ocr/worker.min.js \ --build-arg VITE_TESSERACT_CORE_URL=https://internal-server.example.com/wasm/ocr/core \ --build-arg VITE_TESSERACT_LANG_URL=https://internal-server.example.com/wasm/ocr/lang-data \ --build-arg VITE_OCR_FONT_BASE_URL=https://internal-server.example.com/wasm/ocr/fonts \ -t bentopdf .

Step 3: Export the Docker image

docker save bentopdf -o bentopdf.tar

Step 4: Transfer into the air-gapped network

Copy these files via USB drive, internal artifact repository, or approved transfer method:

  • bentopdf.tar — the Docker image
  • bentopdf-pymupdf-wasm-0.11.14.tgz — PyMuPDF WASM package
  • bentopdf-gs-wasm-*.tgz — Ghostscript WASM package
  • coherentpdf-*.tgz — CoherentPDF WASM package
  • tesseract.js-7.0.0.tgz — Tesseract worker package
  • tesseract.js-core-7.0.0.tgz — Tesseract core runtime package
  • tesseract-langdata/ — OCR traineddata files
  • ocr-fonts/ — OCR text-layer font files
Step 5: Set up inside the air-gapped network
# Load the Docker image
docker load -i bentopdf.tar

Extract the WASM packages

mkdir -p ./wasm/pymupdf ./wasm/gs ./wasm/cpdf ./wasm/ocr/core ./wasm/ocr/lang-data ./wasm/ocr/fonts tar xzf bentopdf-pymupdf-wasm-0.11.14.tgz -C ./wasm/pymupdf --strip-components=1 tar xzf bentopdf-gs-wasm-*.tgz -C ./wasm/gs --strip-components=1 tar xzf coherentpdf-*.tgz -C ./wasm/cpdf --strip-components=1 TEMP_TESS=$(mktemp -d) tar xzf tesseract.js-7.0.0.tgz -C "$TEMP_TESS" cp "$TEMP_TESS/package/dist/worker.min.js" ./wasm/ocr/worker.min.js rm -rf "$TEMP_TESS" tar xzf tesseract.js-core-7.0.0.tgz -C ./wasm/ocr/core --strip-components=1 cp ./tesseract-langdata/*.traineddata.gz ./wasm/ocr/lang-data/ cp ./ocr-fonts/* ./wasm/ocr/fonts/

Run BentoPDF

docker run -d -p 3000:8080 --restart unless-stopped bentopdf

Make sure the files are accessible at the URLs you configured in Step 2, including .../ocr/worker.min.js, .../ocr/core, .../ocr/lang-data, and .../ocr/fonts.

[!NOTE]
If you're building from source instead of Docker, set the variables in .env.production before running npm run build:
>
> VITE_WASM_PYMUPDF_URL=https://internal-server.example.com/wasm/pymupdf/
> VITE_WASM_GS_URL=https://internal-server.example.com/wasm/gs/ > VITE_WASM_CPDF_URL=https://internal-server.example.com/wasm/cpdf/ > VITE_TESSERACT_WORKER_URL=https://internal-server.example.com/wasm/ocr/worker.min.js > VITE_TESSERACT_CORE_URL=https://internal-server.example.com/wasm/ocr/core > VITE_TESSERACT_LANG_URL=https://internal-server.example.com/wasm/ocr/lang-data > VITE_OCR_FONT_BASE_URL=https://internal-server.example.com/wasm/ocr/fonts >

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/

Default Language:

Set the default UI language at build time. Users can still switch languages — this only changes the initial default. Supported: en, ar, be, fr, de, es, zh, zh-TW, vi, tr, id, it, pt, nl, da.

docker build --build-arg VITE_DEFAULT_LANGUAGE=fr -t 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:
