add PDFs in the order you want — merged on your device, never uploaded

Combine several PDFs into one file — chapters into a report, receipts into an expense claim, forms into a single submission. Add them, drag them into the order you want, and download one merged PDF.

The merge runs entirely on your device, so even sensitive documents never leave your computer.

Frequently asked questions

Do my documents get uploaded?
No — combining happens locally in your browser, which makes it safe for contracts, bank statements and other private files.
Can I set the order of the files?
Yes — arrange the PDFs before merging so the pages end up in exactly the sequence you need.
