PDF to Image

Turn a PDF into one or more image files for review, sharing, or AI image analysis.

PDF to Image

What does it do?

The PDF to Image node turns a PDF into image files you can pass to later steps. Think of it like taking clean snapshots of each page so your workflow can read, review, or analyze them visually.

Smart Features

• Can split one PDF into many images: You can export one page per image, or combine pages into grouped images.

• Can merge pages automatically: Choose to group pages as 1, 2, or 4 pages per output image.

• Works with file links from earlier steps: Use a file from Diaflow or a supported web link.

• Skips extra work when the input is already an image: If the incoming file is already an image, the node returns it directly.

• Can reuse recent results: Turn on Enable Cache when the same PDF is converted often.

Real-World Business Value

• Convert invoices or receipts into images before sending them to a vision AI step.

• Turn sales brochures or reports into page images for review in apps or dashboards.

• Break a long PDF into smaller image groups so teams can inspect pages faster.

Step-by-Step Setup

• In the Input field, select the PDF file from an earlier step using @.

• Make sure the file is a PDF link from Diaflow or a reachable web link.

• In Pages per image, enter 1 if you want one page per image.

• Enter 2 if you want two pages combined side by side. This is a good default for faster review.

• Enter 4 if you want four pages combined into one grid image.

• Turn on Enable Cache only if you plan to reuse the same PDF again soon.

• Run the workflow and review the returned image links in the output.

The Transformation: Before & After

Before

Input file:
quarterly-report.pdf

Pages per image:
2

After

[
  "https://.../pdf_page_01.jpeg",
  "https://.../pdf_page_02.jpeg",
  "https://.../pdf_page_03.jpeg"
]

Result:
- Image 1 contains pages 1 and 2
- Image 2 contains pages 3 and 4
- Image 3 contains pages 5 and 6

Tips & Warnings for First-Timers

• Only use 1, 2, or 4 in Pages per image. Other values will fail.

• Use 1 when page detail matters, such as invoices, forms, or dense reports.

• Large PDFs can take longer and may fail if they contain many pages or very large page sizes.

• Password-protected PDFs are not supported. Unlock the file first.

• If you enable cache, older image links can expire later. Turn cache off when you need fresh links every time.

• Use a proper Diaflow file link or a normal web link. Incomplete file paths can fail.

• Slow external file links can delay the workflow. Upload the PDF into Diaflow first when possible.

• If your input may already be an image, this node returns that image as-is. Check the result before assuming a PDF was converted.
