Combine PDFs in the right order
Add two or more PDFs, use the arrows to set the order, then click Merge PDFs. Every page of every file is copied into one new document—text stays selectable and quality is unchanged, because pages are copied, not re-rendered.
Why merge in the browser?
Contracts, payslips and HR forms are confidential. Most online PDF sites upload your files to their servers. This tool uses the open-source pdf-lib library to do the work on your own device, so the files never leave it.
FAQ
Can I merge password-protected PDFs?
No. Remove the password first (open the PDF and print/save it without protection).
Is there a page limit?
No fixed limit; very large files are limited only by your device's memory.
Do links and form fields survive?
Page content, text and images are preserved. Some interactive features such as bookmarks may not be carried over.
