A Docker-based API for PDF
Documentation · Live Demo · Community
Gotenberg is a Docker-based API for PDF. It converts web pages and office documents to PDF, then merges, stamps and signs them, makes them archival or accessible, and delivers them. Trusted in production by thousands of companies, and adopted by notable open-source projects.
Send your files via multipart/form-data, get a PDF back. No need to manage Chromium, LibreOffice, or fonts yourself.
docker run --rm -p 3000:3000 gotenberg/gotenberg:9Convert a URL to PDF:
curl \
--request POST http://localhost:3000/forms/chromium/convert/url \
--form url=https://sparksuite.github.io/simple-html-invoice-template/ \
-o invoice.pdfMake it a PDF/A-2b in the same request:
curl \
--request POST http://localhost:3000/forms/chromium/convert/url \
--form url=https://sparksuite.github.io/simple-html-invoice-template/ \
--form 'stages=[{"op":"remediate","profile":"PDF/A-2b"}]' \
