Docker Converter

Convert documents using markitdown in a Docker container.

Setup (once)

Clone and build the image:

git clone https://github.com/microsoft/markitdown.git /tmp/markitdown
cd /tmp/markitdown
docker build -t markitdown:latest .

Usage

With volume mount (recommended)

docker run --rm -v "$(pwd):/data" -w /data markitdown:latest input.pdf -o output_docker.md

Via stdin/stdout

docker run --rm -i markitdown:latest < input.pdf > output_docker.md

With absolute paths

docker run --rm -v "/path/to/files:/data" -w /data markitdown:latest document.pdf -o document_docker.md

Verify image exists

docker images markitdown:latest

If no image found, run the setup steps above.

Notes

• Container runs as non-root user by default
• All markitdown features are included ([all] dependencies)
• First build takes a few minutes; subsequent runs are fast
