    Merge PDF files

    With Documents, you can easily merge two or more PDF files into one without even opening them - if needed, you can re-arrange the pages manually in your new file to your liking. As for the other file formats, you can convert and merge them into PDF.

    How to merge PDFs

    iPhone iPad
    1. Launch the Documents app.
    2. In the My Filessection or in the folder where the needed files are located, tap ... at the top right > Select.
    3. Choose the files you'd like to merge.
    4. Tap More at the bottom.
    5. Select Merge.

    If one of your files or all of them are forms, you may receive an error while trying to merge them. There's a way you could bypass that: if you want to merge PDF forms, please save them as flattened copies first:

    1. Open a form.
    2. Tap Moreat the top right.
    3. Select  Save a Copy > Flattened Copy.
    4. Now, you can merge this copy with other files as described above.
    Note: The files are merged in a sequence they are selected in - you can re-arrange the pages manually. 
    Tip: If you're getting an error while trying to merge your files and none of them are forms, there's a chance that one of the files is signed with a digital certificate. In some cases, you can simply delete the signature and thus resolve the situation.
