How to merge PDF files
- Choose two or more PDF files, or drop them onto the box.
- Drag the files into the order you want. The first page of each file is shown so you can tell them apart.
- Press Merge. The combined PDF downloads as merged.pdf.
All pages of each file are included, in order. To drop or rearrange individual pages afterwards, open the merged file in Rotate & Reorder PDF.
Questions
Are my PDFs uploaded?
No. The files are combined inside this browser tab and never sent to a server, so contracts, statements, and other private documents stay on your device.
Will the merged PDF look the same as the originals?
Yes. Pages are copied as they are, including text, images, fonts, and links. Nothing is converted or recompressed.
Can I merge password-protected PDFs?
Not directly. Open the file in your PDF reader, remove the password (often under "Print to PDF" or the security settings), and add the unlocked copy.
Can I merge only some pages of a file?
Use Split PDF first to extract the pages you want, then merge the result here.
