Bates Numbering: Stamp Sequential Numbers on PDF Pages
Add Bates numbers to one PDF or a whole set: choose a prefix, a suffix, the starting number, and the number of digits, place the stamp in any corner, and download the stamped files, with numbering carried on from one file to the next.
Bates Numbering: Stamp Sequential Numbers on PDF Pages: Every page gets a label made of the prefix, its number padded with zeros, and an optional suffix: with prefix ABC and six digits, page 123 reads ABC000123. Numbering runs on across files, so files of 12, 5, and 30 pages get ABC000001 to ABC000012, ABC000013 to ABC000017, and ABC000018 to ABC000047. Runs 100% locally in your browser with zero server file uploads.

Nothing is uploaded
Example: ABC000001
Numbers run on from one file to the next in the order listed, so a production set gets one unbroken sequence. The original pages are kept as they are, text stays searchable, and the number is added on top. Nothing is uploaded.
Choosing a format
Pick enough digits for the whole production up front, so every number has the same width and sorts correctly; six digits allow 999,999 pages. Use a prefix that identifies the producing party or the case.
Plain page numbers
For ordinary page numbers that restart in every document, use the PDF page numberer.

A unique, sequential number on every page of a document set, used in legal discovery and other large productions so that any page can be cited and found.
Does it change the original pages?

Can I use non-Latin characters in the prefix?
No: the stamp uses the built-in PDF font, which covers Latin letters, digits, and common punctuation.
