Combining PDFs the right way
Merging joins several PDFs into one document, preserving each page exactly. It's the fastest way to assemble a report from separate exports, combine scanned pages, or bundle invoices and receipts into a single file to send.
Order matters — drag the files into the sequence you want before merging, since pages appear in that order. This tool uses pdf-lib to build the combined document entirely in your browser, so confidential documents are never uploaded.

Frequently asked questions
Are my PDFs uploaded anywhere?
No. Merging happens entirely in your browser using pdf-lib, so your documents stay private.
How many PDFs can I merge?
As many as you like. Very large sets are only limited by your device's available memory.
Can I reorder the files before merging?
Yes — reorder them in the list before clicking Merge, and the final PDF follows that order.
