Add Bates numbers to PDFs privately FAQ

Are my PDFs uploaded for Bates numbering?

No. PDFMech reads, numbers, and creates the new PDFs locally in your browser. The source documents are not sent to a PDFMech processing server.

Can one Bates sequence continue across multiple PDFs?

Yes. Arrange the files in the required order and PDFMech continues the sequence across every selected page in that order.

Can I number only selected pages?

Yes. Use all pages or enter a range such as 1-5, 8, 12 for each PDF before processing.

Will Bates numbering affect digital signatures?

It can. Adding a visible number changes the PDF and may invalidate an existing digital signature, so keep the original signed file.
