What is Merge PDF?
Merging PDFs means joining several documents into one file, with the pages of each appearing one after another. It is the quickest way to send a single attachment instead of five, or to keep a contract, its appendices and a signed cover page together.
Typical uses include bundling invoices for accounting, combining scanned pages into one document, assembling an application pack, and putting chapters of a report in a single file for printing.
How to use Merge PDF (step by step)
Add your PDFs
Drop two or more files onto the upload area, or choose them from your device. You can keep adding more.
Set the order
Use the arrows next to each file to move it up or down. The final document follows this order.
Merge and download
Press Merge PDFs and download the combined file as a single PDF.

Tips for better results
- Name your files with numbers (01, 02, 03) so they arrive in the right order when you select a whole folder.
- Remove blank or duplicate pages first with the Split PDF tool if you only need part of a document.
- Check page orientation if you mix portrait and landscape files. Each page keeps its own orientation.
- Keep an eye on total size. Very large merged files can bounce off email attachment limits.
FAQ
How many PDFs can I merge at once?
You can combine as many files as you like, as long as each one is under 50 MB.
Can I change the order of the files?
Yes. Use the arrows beside each file to move it up or down before you merge.
Will merging reduce the quality?
No. Pages are joined without being re-rendered or recompressed, so the content looks exactly as it did.
Does it work with password-protected PDFs?
Protected files need to be unlocked first. Remove the password in your PDF viewer, then add the file here.
Is the merged PDF watermarked?
Never. The output contains only your pages.
