What is a Bates stamp?

A Bates stamp is a specialized identification mark applied to document pages during legal discovery, pre-trial litigation, and regulatory audits. It applies a unique, sequential alphanumeric code (e.g., PLTF-000142) to each page, creating a permanent, tamper-resistant index that allows attorneys, judges, witnesses, and court reporters to refer to exact document pages without ambiguity.

A standard Bates stamp example consists of: 1) A party/case prefix (e.g., PLTF- or DEF-), 2) A zero-padded numeric sequence (e.g., 000001 to 000450) for database sorting, and 3) An optional confidentiality protective order header (e.g., CONFIDENTIAL - ATTORNEYS' EYES ONLY). A typical stamp looks like PLTF-000042 placed in the bottom-right footer.

Engineered for Legal & Litigation Excellence

Empowering Legal Teams with Free, Private Bates Numbering

We built BatesStampPDF with a single purpose: to give attorneys, paralegals, litigation support specialists, and pro se litigants access to court-grade document stamping without compromising on privacy or paying steep software fees.

01The Origin Story: Why We Built This

In legal litigation, evidentiary exhibits and discovery productions require unambiguous identification through sequential numbering—a practice tracing back to Edwin G. Bates’ manual mechanical stamp machine invented in the late 19th century.

In today's digital courtroom, legal practitioners were left with two deeply flawed options:

Cloud PDF Converters (Severe Security Risk)

Generic online PDF websites upload your files to remote cloud servers, directly jeopardizing attorney-client privilege, HIPAA compliance, and non-disclosure protective orders.

Legacy Desktop Subscriptions ($500+/Seat)

Bloated legacy desktop suites lock simple document numbering behind recurring expensive licensing, complex configurations, and restrictive per-user installs.

We realized that modern web browsers and WebAssembly could run full PDF rendering, geometry scaling, and sequential numbering engines directly in local memory. BatesStampPDF was created to provide a lightning-fast, zero-upload, zero-cost alternative for the entire legal community.
