How to merge PDF files

Put several PDFs into a single file, in exactly the order you choose, without uploading any of them.

Steps

Add your PDFs
Drag two or more PDFs onto the box, or click Choose a file and select several at once. You can pick more later with Add more PDFs.
Set the order
The files are listed top to bottom in the order they'll appear. Use the up and down arrows to move a file, or the X to take one out.
Click Merge PDFs
The files are joined on your device, usually in a few seconds.
Download the result
Click Download to save the merged PDF. The original file is left exactly as it was.

Want to reorder single pages, not whole files? Merge first, then open the result in Organize PDF.
Pages are copied exactly, so text stays selectable and links keep working.
Password protected PDFs need to be unlocked first with Unlock PDF.

Is there a limit on how many PDFs I can merge?: No fixed limit. Very large sets are limited only by your device's memory.
Can I merge images and PDFs together?: Turn the images into a PDF with Images to PDF first, then merge that file with the others.
