File format conversion, document OCR, and audio-to-text — I’ve collected a bunch of different tools, but finding the right one is a hassle.
FileWizard bundles these tools into a self-hosted web page; just drag in a file to convert, with only a few clicks in your browser.
Under the hood, it wraps mature tools like FFmpeg, LibreOffice, and Pandoc, covering a broad set of format conversions.
You can run OCR on images and PDFs, use Whisper to transcribe audio into text, and it includes background tasks and real-time progress.
GitHub: http://github.com/LoredCast/filewizard…
It provides a one-click local deployment via Docker — the project runs on your own machine, so files don’t go to any third party.
If you frequently juggle various file formats, set one up yourself as an online toolbox.

A self-hosted, browser-based utility for file conversion, OCR and audio transcription. It wraps common CLI and Python converters (FFmpeg, LibreOffice, Pandoc, ImageMagick, etc.), plus faster-whisper and Tesseract OCR.
Screenshot
Features
- Convert between many file formats; extendable via
settings.ymlto add any CLI tool. - OCR for PDFs and images (
tesseract/ocrmypdf). - Audio transcription using Whisper models.
- Simple, responsive dark UI with drag-and-drop and file picker.
- Background job processing with real-time status updates and persistent history.
/settingspage for configuring conversion tools and OAuth (runs without auth in local mode).- CPU-only by default; a
-cudaimage is available for GPU use.
Security
Warning: exposing this app publicly without authentication risks arbitrary code execution. Intended for local use or behind a properly configured OAuth/OIDC provider.
Tech stack
FastAPI, vanilla HTML/JS/CSS frontend.
Installation
Recommended — Docker (pull from Docker Hub)
Images available:
loredcast/filewizard:latest(newest full release without cuda)loredcast/filewizard:0.3-small(omits TeX and other large tools)loredcast/filewizard:0.3-cuda(CUDA-enabled)
``
docker-compose.yml
version: “3.9” services: web: image: loredcast/filewizard:latest environment: - LOCAL_ONLY=True # False for Auth - SECRET_KEY= # set if using auth - UPLOADS_DIR=/app/uploads # inside the container - PROCESSED_DIR=/app/processed # inside the container - OMP_NUM_THREADS=1 - DOWNLOAD_KOKORO_ON_STARTUP=true ports: - “6969:8000” volumes: - ./config:/app/config # settings.yml will be here - ./uploads_data:/app/uploads - ./processed_data:/app/processed volumes: uploads_data: {} processed_data: {} ``
Copy docker-compose.yml from the repo or the above, adjust as needed, then:
bash docker compose up -d
FileWizard will be available at localhost:6969
Build locally with Docker (new build types)
For different build configurations, use the BUILD_TYPE argument:
``bash
Full build (includes all dependencies but no CUDA)
docker build –build-arg BUILD_TYPE=full -t filewizard:full .
Small build (excludes TeX and markitdown dependencies for smaller image)
docker build –build-arg BUILD_TYPE=small -t filewizard:small .
CUDA build (includes CUDA support for GPU acceleration)
docker build –build-arg BUILD_TYPE=cuda -t filewizard:cuda . ``
Or with docker-compose:
``bash
For full build
docker compose build –build-arg BUILD_TYPE=full
For small build
docker compose build –build-arg BUILD_TYPE=small
For CUDA build
docker compose build –build-arg BUILD_TYPE=cuda ``
For CUDA builds, ensure you have:
- NVIDIA Docker runtime installed (
nvidia-docker2package) - Compatible GPU with appropriate drivers
- Add the GPU configuration to docker-compose.yml if building with compose:
yaml deploy: resources: reservations: devices: - driver: nvidia count: all capabilities: [gpu]
For troubleshooting GPU issues, make sure:
- Your GPU drivers support the CUDA version (12.1)
- cuDNN libraries are properly installed in the container
- The
nvidia-container-toolkitis properly configured - Test NVIDIA setup with:
docker run --rm --gpus all nvidia/cuda:12.1-base-ubuntu22.04 nvidia-smi
bash git clone https://github.com/LoredCast/filewizard.git cd filewizard docker compose up --build
Note: building can be slow (TeX and other dependencies).
Manual (no Docker)
bash git clone https://github.com/LoredCast/filewizard.git cd filewizard python -m venv venv source venv/bin/activate # Windows: venv\\Scripts\\activate pip install -r requirements.txt chmod +x run.sh ./run.sh
Dependencies include fastapi, uvicorn, sqlalchemy, huey, faster-whisper, ocrmypdf, pytesseract, python-multipart, pyyaml, etc.
