Frequently asked questions

Are my PDFs uploaded anywhere?

No. Merging happens entirely in your browser with pdf-lib. Your documents never touch a server.

Is there a watermark or page limit?

No watermark and no artificial limit. Very large files depend only on your device's memory.

Can I change the order of files?

Yes — use the up/down arrows next to each file before merging.
