Bates numbering for PDF documents

Stamp sequential Bates numbers — SMITH-000001, SMITH-000002… — onto every page of a PDF: set your prefix, digit count and starting number, pick the corner, and download. The Bates mode is pre-enabled below with the standard 6-digit, zero-padded format.

Discovery documents are exactly what shouldn’t pass through a stranger’s server, and with this tool they don’t: stamping runs in your browser, the file never uploads, and you can verify that claim in the Network tab while it works. No per-page fees, no watermarks, no account.

Preset: Bates mode, bottom-right, 6 digits zero-padded — standard production format.

How it works

  1. Drop your PDF above.
  2. Set the prefix (party or matter identifier), digits, and the starting number for this production.
  3. Pick the corner — bottom-right is the convention the preset uses.
  4. Click “Stamp Bates numbers” and download. Note the last number used for your log.

Conventions that keep productions clean

Standard practice (checked against current e-discovery guidance, July 2026): a short uppercase prefix identifying the producing party or matter (ABC-, PLTF_), at least six zero-padded digits — eight for very large matters — and numbering that continues across productions rather than restarting. ABC-000001 instead of ABC-1 is what keeps files sorting correctly everywhere. Many ESI protocols specify all of this explicitly; where yours does, it controls.

Continuing a production: set “Start at” to the next number after your previous batch ended. The stamp is drawn into the page content in Helvetica, a standard base font every viewer supplies — permanent, printable, and readable by every review platform.

Frequently asked questions

Where should Bates numbers go on the page?

Bottom-right is the widespread default (and this page’s preset); bottom-left appears in some protocols. What matters most is consistency across the production — and not covering content, which the margin setting controls.

Can the stamp overwrite something important on a page?

The stamp sits inside the margin you choose, but crowded pages exist — spot-check pages with edge-to-edge content. The “wide” margin setting clears most footers; if a page truly has no clear corner, protocols generally accept placing the number in the least-obstructive position.

Does this handle rotated (landscape) pages correctly?

Yes — the stamp is placed relative to each page as it displays, so a landscape exhibit inside a portrait production still gets its number in the visual bottom-right, right-side-up.

Is browser-based stamping defensible for discovery?

The output is a standard PDF with permanent stamps, identical in kind to desktop-tool output. What browser-based adds is that documents never leave your custody during stamping — a chain-of-custody positive. Your ESI protocol and review workflow still govern the rest.
