  "description": "Formfeed is an API that renders PDFs and images from HTML templates written in Jinja2, Liquid or Handlebars and JSON data, fills Word and PowerPoint templates, converts office documents to PDF, merges, protects and watermarks PDFs, and turns an invoice into a ZUGFeRD / Factur-X e-invoice that is validated before it is delivered. Rendering runs in Frankfurt, rendered files are stored in the EU, prices are in EUR and there is a free plan. Around the API: a browser editor, a command line tool for templates as files, SDKs for TypeScript and Python, and an MCP server for AI agents.",
