How to merge PDF files in Make

To merge PDF files in a Make scenario, use the 1001fx function mergepdfs. It takes two or three PDF files and returns one PDF in which every page keeps its orientation.

  1. 1

    Get your API key

    Create a free 1001fx account and copy your API key from the app.

  2. 2

    Start the scenario

    Start with the modules that deliver the PDF files, for example Google Drive "Watch files in a folder" followed by "Download a file" for each PDF.

  3. 3

    Add the 1001fx module

    Add a module, search for 1001fx and pick “Merge PDFs”. Select your 1001fx connection or create one with your API key.

  4. 4

    Fill the fields

    file1
    – The first PDF, with file name and data from the download module.
    file2
    – The PDF that is appended after the first one.
    file3

Tips

  • To merge more than three PDFs, merge the first ones and then merge the result with the next files in a second call.
  • Use removepdfpages or insertpdfpages if you need only some pages of a file.

Frequently asked questions

How many PDFs can I merge in one call?
Up to three: file1 and file2 are required, file3 is optional. For more files, merge the result again with the next ones.
Are landscape pages kept?
Yes. Every page keeps its orientation, so landscape and portrait pages can be mixed in the merged PDF.
