Merge PDF
Combine several PDFs into one file, in the order you choose.

Your file is ready.
Try a different file, or try again.
How it works
Drop or choose your PDF files (20 at a time, each under 80 MB).
Reorder them with the move-up/move-down buttons - the order you set is the order they merge in.
Click Merge and download the combined PDF.
Frequently asked questions
20 files at once, each under 80 MB.

No. Pages are copied as-is into the new file - nothing is re-rendered or re-compressed.
