Frequently Asked Questions

How many PDF files can I merge at once?

There is no hard limit. You can merge as many PDFs as your browser memory supports. Most users merge 2-20 files without issues.

Can I reorder pages before merging?

Yes. Drag and drop files to change the merge order. The final PDF will contain pages in the order you arranged the files.

Is merging PDFs free and private?

Yes. Merging uses pdf-lib running in your browser. Files never leave your device. No signup required and no limits on file size or document count.

Can I merge password-protected PDFs?

Password-protected PDFs need to be unlocked before merging. Remove the password protection first then merge the unlocked files.
