How to use the Merge PDF tool
-
Choose the PDF files
Tap Choose PDF files and select 2 or more files, or drop them on the box. You can add up to 50 files.
-
Set the order
The first file in the list gives the first pages. Move a file with the up and down arrows.
-
Merge
Tap Merge PDF. The tool copies every page of every file into one new PDF.
-
Download
Tap Download to save merged.pdf, or Share to send it to another app.
What happens to the pages?
The tool copies each page as it is: the same size, the same orientation, the same text and images. An A4 page and a Letter page can sit in the same PDF. The tool does not compress the pages, so the size of the new PDF is close to the total size of the files.
Links on a page stay. Bookmarks and fillable form fields do not carry over, so fill a form before you merge it.
What if a PDF has a password?
The tool cannot open a PDF with a password, and it tells you which file it is. Remove the password first. In the PDFriend app for Android and iPhone, the Unlock tool does it, if you know the password.
Can you merge images and PDF files?
Not in one step. Make a PDF from the images first with JPG to PDF, then merge that PDF with the other files here.
