# Merge PDF documents Combine up to ten PDF documents into one, in the order you supply them, in a Power Automate flow. Use this action to combine multiple PDF documents into a single PDF document. The documents are merged in field order, from the 1st File Content to the 10th. <PowerAutomateAction title="Merge PDF documents" caption="Merge PDF documents." fields={[ { label: "1st File Content", kind: "token", value: "1st File Content" }, { label: "2nd File Content", kind: "token", value: "2nd File Content" }, { label: "3rd File Content", placeholder: "The content of the 3rd PDF document" }, { label: "4th File Content", placeholder: "The content of the 4th PDF document" }, { label: "5th File Content", placeholder: "The content of the 5th PDF document" }, { label: "6th File Content", placeholder: "The content of the 6th PDF document", advanced: true }, { label: "7th File Content", placeholder: "The content of the 7th PDF document", advanced: true }, { label: "8th File Content", placeholder: "The content of the 8th PDF document", advanced: true }, { label: "9th File Content", placeholder: "The content of the 9th PDF document", advanced: true }, { label: "10th File Content", placeholder: "The content of the 10th PDF document", advanced: true }, ]} /> <Note> The first 5 file fields are displayed by default. To display fields 6 to 10, turn on **Show advanced parameters**. </Note> <Tip> Merging documents that come from a loop or an earlier action? Use [Merge PDF documents from an array](/docs/power-automate/merge-pdf-documents-from-an-array) instead. It takes a single array and isn't limited to 10 documents. </Tip> ## Parameters <ParamField name="1st to 10th File Content" type="File"> The content of the PDF documents to merge. Each field is optional, and the merged document keeps the field order. </ParamField> ## Response <ParamField name="Merged PDF File Content" type="File"> The content of the merged PDF document.
