Merge PDF

Combine several PDFs into one. Files never leave your device.

About this merge pdf

Merging combines the pages of several PDF files into one document, in the order you choose. Use it to join chapters, scans, receipts or application documents into a single file you can send or print. Pages are copied as they are, so text, images and layout stay unchanged. Everything runs in your browser, so confidential files are never uploaded.

How to use it

  1. Add two or more PDF files.
  2. Use the arrows to put them in the right order.
  3. Press Merge PDFs to download the combined file.

Tips and good to know

Before merging, check the page order inside each file. Scanned documents are often easier to handle if you merge first and then use Rearrange PDF Pages to fix the order. Merging does not compress files, so the result is roughly the sum of the originals. If a file will not load, it may be password protected or damaged, and re-saving it from a PDF viewer usually fixes it.

Frequently asked questions

Is there a file size limit?

There is no fixed limit, but very large files depend on your device memory.

Can I merge password-protected PDFs?

No. Remove the password first, then merge.
