PDF Bates Numbering — Stamp Tool for Lawyers

About

Local-first processing — your Privileged PDFs never leave your browser.
Just $39.99 one-time. No yearly PDF subscription. Lifetime access.
Stop paying expensive yearly fees just to stamp Bates numbers on Discovery documents.

PDF Bates Numbering is a no-cloud Bates stamping tool built for US litigators, paralegals, and Discovery teams who can't risk uploading client files to a third-party server.

Process every PDF entirely in your browser using PDF-lib. Nothing is uploaded. Nothing is logged. Documents subject to attorney-client privilege, HIPAA confidentiality obligations, or trade-secret protection stay on your machine — supporting your reasonable-efforts obligations under ABA Model Rule 1.6(c).

★ FREE PLAN
• Stamp up to 10 PDFs per month
• Custom prefix and optional suffix (e.g., SMITH-DEF-000001-CONFIDENTIAL)
• Configurable starting number and zero-padding
• Six stamp positions (bottom-right is the standard for Discovery)
• Three opacity levels (100% / 75% / 50% — for drawings and photos)
• Per-page continuous numbering within each batch
• 1-page preview before stamping

★ PRO PLAN — $39.99 ONE-TIME
• Unlimited PDFs per month
• Saved case presets — save up to 20 prefixes (SMITH-DEF-, JONES-PLT-, …)
• Per-case continuous numbering — each saved preset remembers its last Bates number, so the next batch automatically picks up where the previous one left off
• Lifetime updates, no recurring fees

★ HOW IT WORKS
1. Click the toolbar icon or press Ctrl+Shift+Y (Mac: Cmd+Shift+Y)
2. Drag and drop one or more PDFs into the standalone window
3. Set your prefix (ASCII characters only, e.g., SMITH-, DEF-), starting number, and stamp position
4. Click Stamp — files are processed locally and saved to your Downloads folder

★ WHY LITIGATORS CHOOSE THIS OVER EXPENSIVE PDF SUITES
• Local-only — privileged, PHI-bearing, and trade-secret documents never leave your browser
• One-time $39.99 vs. an expensive yearly subscription (and rising fees)
• No account, no login, no analytics, no telemetry
• No "AI features" sending your Discovery to any third-party LLM service
• Works offline — suitable for restricted, offline-capable review environments

★ WHO IT'S FOR
• Solo and small US law firms handling Discovery
• Mid-size firm paralegals stamping production sets
• IP litigators protecting trade-secret exhibits
• Medical malpractice attorneys handling records subject to HIPAA
• Family law attorneys managing sensitive financial disclosures
• Insurance defense, employment, and commercial litigators
• In-house counsel preparing internal investigations

★ WHAT IT'S NOT
• Not a redaction tool (use specialized redaction software for true redaction)
• Not a full PDF editor — single purpose: Bates stamping only
• Not cloud-based — there is no server, by design
• Password-protected (encrypted) PDFs are not supported. Decrypt your PDFs first using another PDF tool before stamping.

★ PRIVACY-FIRST BY ARCHITECTURE
There is no server to send your PDFs to. Stamping happens entirely inside your Chrome browser using the PDF-lib library bundled with the extension. The only network request the extension ever makes is to ExtensionPay (Stripe) for the one-time $39.99 purchase — and even then, no PDF content, file name, or document data is shared.

Note: Uninstalling the extension removes saved prefix presets and usage counters. Your stamped PDFs remain in your Downloads folder.
