pdftotext. As a webservice, containerized! The image is based on Alpine. See also image on Docker Hub: sdenel/pdftotext-docker-rest
docker run -d -p8888:8888 sdenel/pdftotext-docker-rest:latest
Then, to test it:
wget http://www.xmlpdf.com/manualfiles/hello-world.pdf
curl -F "[email protected];" http://localhost:8888/
- Still to do: allow usage of pdttotext options.
