Questions
Are my PDFs uploaded?
No. The files are combined in your browser with the open-source pdf-lib library, so contracts and invoices never leave your device.
Is there a size limit?
There is no fixed limit, but everything happens in your device’s memory. Combining a few hundred megabytes works on a computer; on a phone keep it to smaller files.
Can I merge password-protected PDFs?
Not reliably. Remove the password first in the app that created the file (or with Print, Save as PDF), then merge.
