Frequently asked questions

Are my PDFs uploaded to a server?

No. Merging is done inside your browser with the pdf-lib library. Your documents never leave your device, so it is safe even with confidential files.

Is there a file or size limit?

We do not impose an artificial limit. The only practical limit is your device's memory, since everything happens locally.
