Questions

Does my PDF get uploaded?

No. Paradoc runs in this browser tab. The page loads its own code from paradoc.online, and then your PDF is read and written on your device, by PDFium, the engine behind Chrome's PDF viewer, built into WebAssembly. You can check: open your browser's network panel, and watch for a request carrying your file. There isn't one (the page only fetches its own code).

How many files can I merge?

Up to 20 PDFs at a time, 100 MB in total.

Can I merge password-protected PDFs?

Yes. You enter each password once, in this tab, and the merged PDF comes out without a password.

Does it work on iPhone and Android?

Yes. Open this page in Safari or Chrome on your phone and pick the files from Files or your downloads.
