Frequently Asked Questions
Are my PDFs uploaded to a server?
No. The merging happens entirely inside your browser. Your documents never leave your device, which makes this safe even for confidential files.
Can I change the order of the files?
Yes — use the up/down arrows next to each file to arrange them before merging. Pages are combined in the order shown.
Is there a file size or page limit?
There is no artificial limit. Very large files are only constrained by your device's memory, since all processing is local.
