Question 1

Can I reorder PDFs before merging?

Accepted Answer

Yes. Drag files or use the up/down arrows to set the final order. The merged PDF follows that sequence page by page.

Question 2

How many PDFs can I merge?

Accepted Answer

Up to 20 PDFs in one go, with a 100 MB limit per file. All processing happens in your browser.

Question 3

Is merging private?

Accepted Answer

Yes. Your PDFs are never uploaded. Merging runs locally with pdf-lib on your device.
