Bates numbering

Yes, that is the point of it. Drop several PDFs and the count runs straight through them in the order you dropped them: if the first file has 12 pages and you start at 1, the second file begins at 13. A skipped cover sheet does not spend a number, so the sequence has no holes. Each file still comes back separately, with a -bates suffix.

With prefix and digits. The prefix is a literal string put in front, and digits is the zero-padded width, which defaults to 6. There is a suffix too. So a prefix of ABC and a suffix of -CONF gives ABC000001-CONF. A number too long for the width is not truncated, it simply gets wider.

Bottom right by default, 24 points in, in Helvetica at size 9, which is the convention for a legal control number. Any of six corners and edges will take it, at the size, margin and colour you set. Switch on the white plate where it lands on a dark scan and would otherwise be unreadable.

Start must be a whole number of 0 or more and digits a whole number of 1 or more, each with a message saying exactly that. Size must be above zero, margin zero or more, and colour six hex digits. The prefix and suffix take any text you want, including none.

No. Every file is loaded, stamped and saved by pdf-lib inside a Web Worker in this tab. That matters here, since Bates numbering is usually applied to discovery material. Nothing is transmitted, no copy is kept, and the tool runs with your network switched off.

Add page numbers works on one file at a time and restarts its count for each file. This runs one continuous sequence across a whole set, padded to a fixed width with a prefix and suffix. Use this when the number has to be unique across a production set rather than within one document.
