Convert PDF to Images
The Convert PDF to Images block takes a PDF document — provided as a URL — and converts each page into a separate PNG image.
Convert PDF pages into PNG images via URL
The Convert PDF to Images block takes a PDF document — provided as a URL — and converts each page into a separate PNG image. The resulting images are hosted on a CDN, and the block returns an array of URLs, one for each page in the document. This makes the content of any PDF accessible as standard image files that other blocks in a workflow can process further.
The block has two interface fields: a required pdfUrl string pointing to the source PDF, and an optional destinationVar where the output array of image URLs can be stored for use later in the workflow. The output field, imageUrls, is an array of strings, with each entry corresponding to one page of the original document in order.
This block fits into workflows that need to extract visual content from PDFs for downstream processing — for example, passing pages to an image analysis block, displaying document previews in an application, or feeding pages into an AI vision model. It is particularly useful any time a workflow receives a PDF but needs to work with its contents at the page level as images.
What you can build
Real-world workflows powered by the Convert PDF to Images block.
AI Document Review
Convert uploaded PDF reports into page images and pass each image to a vision model for automated content extraction or summarization.
PDF Preview Generation
Generate image previews of each PDF page to display document thumbnails inside a user-facing application built on MindStudio.
Invoice Data Extraction
Convert PDF invoices to images and route each page to an OCR or vision block to extract line items, totals, and vendor details.
Contract Page Analysis
Break multi-page contract PDFs into individual page images so an AI model can analyze each page for key clauses or signatures.
Slide Deck Processing
Convert presentation PDFs into per-slide images for use in workflows that generate summaries or speaker notes from each slide.
Compliance Document Scanning
Transform regulatory or compliance PDFs into images and pass them to a classification block to flag pages requiring human review.

What parameters does this block require?
The block has one required parameter: pdfUrl, a string containing the URL of the PDF document to convert. There is also an optional destinationVar field where you can specify a variable name to store the resulting array of image URLs for use later in the workflow.
What does the block return?
The block returns an output field called imageUrls, which is an array of strings. Each string is a CDN URL pointing to a PNG image of one page from the source PDF, in page order.
How are the output images delivered — do I need to host them myself?
No. Each page image is automatically hosted on a CDN by the block, and the returned URLs point directly to those hosted images. You do not need to configure any storage or hosting separately.
What kinds of workflows commonly use this block?
This block is commonly used in workflows that need to process PDF content visually — such as passing pages to AI vision or OCR blocks, generating document previews for end users, or analyzing specific pages of multi-page documents like invoices, contracts, or reports.
Does the block support PDFs with multiple pages?
Yes. Each page of the PDF is converted to a separate PNG image, and the imageUrls array will contain one URL per page, regardless of how many pages the document has.
