How to merge PDF files
Choose the files
Pick the PDFs from your documents or upload them. You can combine up to 50 files at once.
Put them in order
Drag the files into the order they should appear in the combined document.
Merge and download
PDFZyro joins them into one new PDF in the background. Open it, keep working on it, or download it.
Merging without the hassle
Up to 50 files at once
Combine many documents in one go, with thousands of pages in total.
Your order
Arrange the files before merging, then reorder, rotate or delete pages in the result if you need to.
Originals untouched
Merging creates a new document. The files you started from stay exactly as they were.
Then do more
Add page numbers or Bates numbers, compress the result, or send it for signature, all in the same place.
Bookmarks for each file
Each file you merged gets a bookmark with its name, and its own bookmarks are kept underneath, so the combined PDF is easy to find your way around.
Private by design
Encrypted and private
Every file is encrypted before it's stored, and only you and the people you share with can open it.
Your original stays safe
Every change is saved as a new version. The original is never changed, and you can restore it at any time.
No watermarks
Files you save never get a watermark, on any plan, including the free one.
Works in your browser
Nothing to install. Use it on Windows, Mac, Linux, Chromebooks, iPhone, iPad and Android.
