About this PDF merger
This tool joins several PDF documents into one file directly in your browser. Each PDF you add is read on your device, its pages are copied in the order you set, and a new combined document is generated locally. Because nothing is sent to a server, even confidential contracts, invoices, or scans stay completely private.
Merging PDFs is useful whenever separate files really belong together — combining chapters into one book, attaching receipts to an expense report, or bundling a signed form with its supporting documents. Reordering before merging means you never have to re-scan or reprint anything.
The output keeps the original page content and dimensions of each source file, so a merged document looks exactly like the originals placed end to end. There is no watermark and no page limit beyond your device's memory.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser. Your documents never leave your computer, which makes this safe for sensitive files.
Can I change the order of the files?
Yes. Use the up and down arrows next to each file to arrange them before merging. Pages are combined in the order shown.
Is there a watermark on the result?
No. The merged PDF contains only your original pages, with no added watermark or branding.
Can it merge password-protected PDFs?
It can open many protected files for merging, but PDFs with strong encryption may fail to load. Remove the password first if a file cannot be added.
How many files can I combine?
There is no fixed limit. Very large documents depend on the memory available in your browser.
