## Parameters

<ParamField name="File Content" type="File" required>
  The content of the input PDF document.
</ParamField>

<ParamField name="Maximum Bytes" type="Integer Number" required>
  The maximum size in bytes of each output PDF document (for example `1048576` for 1
  MB). A single page larger than this size is returned as its own part that exceeds
  the limit. The value is 1 or more.
</ParamField>

## Response

This action returns a list of PDF documents. Add an **Apply to each** over the
**Documents** output to process every part.

<ParamField name="Documents" type="Array">
  The output PDF documents, in order. Each item has:

  - **File Name** — the name of the PDF document (`00001.pdf`, `00002.pdf`, and so on).
  - **File Content** — the content of the PDF document, which you can use as an input to other actions.
  - **Content Type** — the media type of the document (`application/pdf`).
