Frequently asked questions

How many PDFs can I merge?

You can merge multiple PDFs in one session. Very large sets may take longer because work runs on your device.

Is merge order preserved?

Are my files uploaded?

No. Merging happens locally in your browser.

Can I merge password-protected PDFs?

Unlock them first with Unlock PDF, then merge the unlocked copies.
