How to merge PDF files

  1. Choose your PDF files, or drop them onto the box.
  2. Put them in order with the up and down arrows. The first file becomes the first pages.
  3. Press Merge PDF, then Download. You get one file called merged.pdf.

Private by design

Most online PDF tools upload your documents to their servers. This one doesn’t: the merge runs inside your browser, so contracts, invoices and scans stay on your computer or phone. You can even disconnect from the internet after the page has loaded and it still works.

What gets kept

  • Every page, in the order you set, at its original size and rotation.
  • Text, fonts, images and vector graphics, unchanged.
  • Links inside a page usually keep working. Bookmarks (the outline panel) and form fields are not carried over yet.

Questions and answers

Are my PDF files uploaded anywhere?
No. The files are read and merged by your browser on your own device. Nothing is sent to a server, which is also why there is no upload wait.
Can I merge password-protected PDFs?
Not yet. Remove the password in your PDF reader first (you need to know it), then add the file again.
Will the quality of my pages change?
No. Pages are copied as they are: text stays text and images keep their original resolution. Nothing is re-compressed.
Is there a limit?
Up to 20 files and 100 MB in total per merge. Very large files depend on how much memory your device has.
