PDF Merger stitches several PDFs into one, right in your browser, in the order you choose: the contract, the signed page, and the appendix become a single file.

How to use it

Open PDF Merger and pick your PDFs.
Arrange the files in the order you want with the up and down buttons.
Merge, then download the combined PDF.

Good to know

One action per merge. Adding, reordering, and checking page counts are free.
Pages are copied exactly as they are: no re-compression and no quality loss.
Password-protected PDFs need to be unlocked first, then merged.

Your data

Your files never leave your device. Merging happens in your browser.

Tips

Put the signed page last and the contract first, the way a reader expects, and nobody has to shuffle loose pages again.
Merging the attachments from a client email thread into one PDF before you send them on saves the next person the same shuffle.

Questions

Do my PDFs upload anywhere? +

No. The merge runs in your browser.

Is there a size limit? +

Only what your device can comfortably hold in memory. Ordinary contracts and reports are no problem.
