How to use this tool
Select your PDFs
Choose two or more PDF files, or use the public sample below.
Check the order

Merge and check
Select Process file, download merged.pdf and check the page count and the join between documents.

Frequently asked questions
Can I change the file order here?
Files are appended in the order shown in the selection summary. The current merge tool has no reorder list. Reselect in the required order, or use Reorder PDF afterward.
Will this make a smaller file?
Merging is not compression. The result size depends on the source PDFs and their shared resources.
Are my PDFs uploaded?
The conversion code reads and combines files in your browser. Loading the site, its engines and advertising scripts still makes network requests.
Can I use a phone?
Yes, the same file picker and processing controls are available on mobile. Start with small files because available browser memory varies.
