    How to Convert PDF to Image in n8n (PNG/JPG Workflow Guide)

    Transform PDF pages into images for previews, social cards, OCR pre-processing, and document review tasks.

    PDF-to-image conversion is a common step for preview generation and visual pipelines. With n8n, you can process every uploaded PDF automatically.

    Flow template

    Trigger → PDF to Image API → Iterate pages → Store/Send images

    • Pick output format based on use case: PNG for quality, JPG for size
    • Use page filters for only the first or selected pages
    • Set DPI to balance readability and file weight
    POST /api/v1/pdf/to/image
{
  "url": "https://example.com/source.pdf",
  "format": "png",
  "dpi": 200
}

    Operational tips

    • Keep a max-pages guardrail for long documents
    • Use background queues for high-volume batches
    • Send page thumbnails to approval steps

    Conclusion

    Start from PDF to Image API and wire conversion outputs to your n8n delivery stack.
