When to Merge PDF Files?
Combining PDF documents is useful in many situations: compile several reports into one file, merge invoices for your accounting, put scanned pages back together, or join the chapters of a manuscript. One file is easier to share, print and archive than a dozen.
Because PDFs.app works entirely in your browser, even confidential documents such as contracts, bank statements or medical records stay on your computer.
Need to tidy up the result? Organize the pages, delete pages you don't need, or compress the PDF to make it small enough for email – just click one of the suggestions that appear after merging.
Frequently Asked Questions about Merging PDFs
Is there a limit to the number of files I can merge?
There is no hard limit. Very large or very many files are limited only by your device's memory – merging dozens of typical documents works without problems.
Will the quality of my PDFs be affected?
No. Pages are copied as they are, without re-compressing images or text, so the merged PDF looks exactly like the originals.
Can I merge password-protected PDFs?
Encrypted PDFs have to be unlocked first. Open them with your password in a PDF reader, save or print a copy without protection, and merge that copy.
Are links and bookmarks kept?
Links inside the pages keep working, including links that jump to another page of the same document. The bookmark sidebar (outline) of the original files is not carried over to the merged PDF.
Are my files uploaded anywhere?
No. The merge happens locally in your browser using JavaScript. Your documents are never sent to a server.
