Render a document as PDF
Convert a document into a PDF suitable for inline preview.
Accepts a file upload (multipart/form-data), a document URL, or a file_id referencing a document already ingested in the platform (JSON body). The conversion is synchronous — the PDF bytes are returned directly.
Supported file types: .pdf, .png, .jpg, .jpeg, .pptx, .ppt, .odp, .docx, .odt, .doc, .html, .xhtml
Size limit: 20 MB.
