PDF Merger FAQs

How many PDFs can I merge?

You can add as many files as your browser memory allows. For smoother performance, merge large batches in smaller groups.

Can I reorder pages after merging?

Reorder entire files before combining them. If you need page-level control, use our PDF splitter first, then merge pages in the order you want.

Does the tool support password-protected PDFs?

Locked PDFs can be merged once you enter the password. We never store the password—it stays in your browser session only.

Will merging change the file quality?

No. Pages are combined without recompression, so images and text keep their original fidelity.
