How to Merge PDF Files on iPhone

Join related PDF files into one organized document without using a desktop computer.

Quick answer

Select the PDFs in a merge tool, arrange the files in the desired sequence, create the combined PDF, and verify the page count and transitions before sharing.

Step-by-step instructions

  1. Collect the source PDFs

    Place the documents where they are easy to identify and confirm that every file opens correctly.

  2. Open the merge tool

    Choose merge PDF in PDF Scanner.

  3. Select the files

    Add only the PDFs that belong in the final document.

  4. Arrange their order

    Move the files into the intended sequence before combining them.

  5. Create the merged PDF

    Run the merge and wait for the combined file to finish.

  6. Review and rename

    Check the total page count and the boundary between each source document, then use a descriptive filename.

Tips for a better result

  • Number source filenames first when merging many files.
  • Remove duplicate pages before sending the final document.
  • Compress the merged result if its combined size exceeds a sharing limit.
