FAQ

HTML to PDF API questions

What is an HTML to PDF API?

An HTML to PDF API turns HTML (or Markdown) into a print-ready PDF over HTTP. ForgeDocs accepts template packs, raw HTML, or Markdown on POST /api/v1/render and returns a PDF or PNG — no drag-drop editor required.

How does the invoice PDF generator work?

Send JSON for the invoice pack (company, client, line items, tax, totals). ForgeDocs renders a production-looking invoice PDF via the same Chromium pipeline used by MCP tools like generate_invoice.

Do you offer a certificate generator API and packing slips?

Yes. Opinionated certificate and packing-slip packs ship with schemas agents already understand. Call them over REST or MCP without designing layouts from scratch.

Can I generate Open Graph images?

Use the og-card pack for 1200×630 PNGs — a simple Open Graph image API for social previews, docs, and agent-generated pages.

Is there Markdown to PDF and merge PDF support?

Pass a markdown field for styled Markdown → PDF. For combining files, POST /api/v1/merge (and MCP merge_pdfs) merges multiple PDFs into one.
