or drag & drop — pasting works too (Ctrl+V)

How to merge two PDF files into one

Select both PDFs, drag them into the order you want, and click Merge — your combined document downloads instantly. Works just as well with three, ten or fifty files. Because merging happens in your browser, contracts and statements never touch a server.

Frequently asked questions

Can the two PDFs have different page sizes?

Yes — pages keep their original sizes in the combined document.

Is there a file size limit?

No fixed limit. Large files simply take a few seconds longer since your own device does the work.
