Bates numbering is the convention that makes a document set citable. Every page in a production gets a unique, sequential identifier — usually a prefix, a zero-padded number and sometimes a suffix, as in ACME-000142 — so that a lawyer, an auditor or a court can refer to one page out of forty thousand without ambiguity. This tool applies that across your files, continuing the sequence from one document into the next rather than restarting.

You can hand it several PDFs and either keep them separate, each carrying its slice of the numbering, or merge them into a single production file. A page range is optional, and if a range runs past a file's last page it is clamped for that file instead of throwing the whole run.

How it works

  1. Drop in one or more PDFs, in the order the production should follow.
  2. Set the prefix, any suffix, and how many digits the number should be padded to.
  3. Optionally give a page range, and decide whether to merge everything into one PDF.
  4. Apply and download.

What people use it for

  • Numbering a document production for litigation or discovery.
  • Giving an audit bundle stable page references that survive reprinting.
  • Making a long submission citable so reviewers can point at a specific page.

Frequently asked questions

Is my file uploaded to a server?
No. The file is opened by JavaScript and WebAssembly running inside your own browser tab. It is never uploaded, there is no server-side processing and nothing is stored — closing the tab discards everything.
How is this different from page numbers?
Page numbers restart per document and describe position. Bates numbers are unique identifiers that run across an entire set, which is what lets somebody cite one page unambiguously six months later. That is why the prefix and the padding matter.
How many digits of padding should I use?
Enough for the whole production plus room to grow. Six digits is the common default; the point is that every identifier sorts correctly as text, which is what padding buys you.
What happens if my page range goes past the end of a file?
It is clamped for that file and the run continues. A range of 1-50 applied to a 30-page document numbers its 30 pages rather than failing.
Can I number several files as one continuous sequence?
Yes — that is the normal case. The order you add the files is the order the numbering follows, and you can choose whether the result stays as separate files or becomes one merged production.
