Frequently Asked Questions
Can I change the order of the PDFs before merging?
Yes. Use the up/down arrows next to each file to reorder it before merging — the output follows that order.
Are any pages lost or reordered during a merge?
No. Every page from every file is copied into the merged PDF in the order the files are listed, with nothing dropped.
Are my PDFs uploaded to a server?
No. Files are merged entirely in your browser using JavaScript — nothing is uploaded.
Does it work with password-protected PDFs?
No. Encrypted/password-protected PDFs aren't supported — remove the password first using your PDF viewer, then merge.
