About Bates numbering
Bates numbering stamps a unique, sequential identifier on every page across a set of documents — standard practice in legal discovery and records management so any page can be cited unambiguously.
You set the prefix, starting number, digit count, and position, and the identifiers are drawn onto each page in your browser. The tool can carry the sequence across multiple files so the numbering stays continuous. The documents are never uploaded.

Bates Numbering — frequently asked questions
What is Bates numbering?+
A sequential numbering scheme — a prefix plus a zero-padded number, like ABC000001 — that law firms and courts use to uniquely identify and reference every page across a set of documents.
Can I number multiple files as one continuous sequence?+
Yes — add several PDFs and the numbering continues across all of them in the order they're listed, so file two picks up where file one left off.
Can I customize the prefix and number of digits?+
Yes — set any prefix text and choose how many digits to zero-pad to (e.g. 6 digits gives 000001), plus the starting number and position on the page.
Is this the same as regular page numbers?+
No — Bates numbers are typically a longer, prefixed, zero-padded sequence meant for legal document identification, while the Page Numbers tool is a simpler running count. Use whichever format your situation calls for.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
