PDF Generate Tools

The PDF Generate provider builds a simple, paginated PDF document entirely server-side (using pdf-lib) from a title and newline-separated paragraphs, and returns the file as a base64 string. Use it in a workflow when you need to turn generated or collected text into a downloadable PDF without calling an external API. This tool backs the PDF format option of the Document Generator block.

Overview

Operations

Configuration

pdf_generate

Notes:

• Both title and content have user-or-llm visibility, so they can be filled in manually or produced by an upstream LLM/agent block.
• No secret parameters. This tool does not take an apiKey, token, or password and makes no outbound HTTP request.

Outputs

pdf_generate

• base64 (string) — Base64-encoded PDF file contents.
• filename (string) — Suggested filename for the PDF. Derived from title (e.g. My Report.pdf); falls back to document.pdf when no title is provided.
• mimeType (string) — MIME type of the generated file. Always application/pdf.

YAML Example

pdf_generate_1:
  type: pdf_generate
  name: "PDF Generate"
  inputs:
    operation: "pdf_generate"
    title: "Quarterly Summary"
    content: "First paragraph of the report.\nSecond paragraph with more detail."
  connections:
    outgoing:
      - target: next-block-id

Tips

• No authentication required: this tool runs entirely server-side via pdf-lib, so there is no API key, token, or external API to configure.
• Use newlines to control paragraphs: every \n in content starts a new paragraph. Content automatically flows onto additional A4 pages when it overruns the current page.
• Consume the result by reference: downstream blocks read the file via {{pdf_generate_1.base64}} (for example to upload or email an attachment), and {{pdf_generate_1.filename}} / {{pdf_generate_1.mimeType}} for metadata.
• In the visual builder this is exposed as the Document Generator block; selecting the PDF format maps to the pdf_generate tool id. The same block also offers docx_generate and pptx_generate for other formats.
