FAQ

FAQ

Are my files uploaded?

No. The PDF is processed entirely in your browser and never sent to a server.

Can I skip the cover page when numbering?

Yes. Enter 2- under Pages to number and set the start number to 1, so the second page becomes page 1.

Can the watermark be removed later?

It's drawn onto the page content, so it can't be switched off like a layer, but someone with PDF editing software could still remove it. Keep your original file if you need a clean copy.
