About This Tool
This legal document utility applies sequential Bates discovery numbering, court exhibit labels, and confidentiality notices to PDF documents. Law firms, paralegals, and corporate legal departments preparing document productions for litigation or regulatory compliance can stamp thousands of pages without sending sensitive discovery materials to third-party cloud servers.
### Processing Engine and Configuration Options The tool modifies PDF files directly in local memory using the `pdf-lib` JavaScript library:
- **Stamp Types:** - *Bates Numbering:* Generates sequential identifiers with custom prefixes (such as `DEF-DISCOVERY-`), customizable starting numbers, and padded digit counts (e.g. 6 digits). - *Exhibit Badge:* Formats labels as `[ EXHIBIT A - PAGE X OF Y ]` with custom exhibit identifiers. - *Confidentiality Notice:* Applies `CONFIDENTIAL - ATTORNEYS' EYES ONLY • [BATES-NUM]`. - **Page Alignment:** Positions stamps at bottom-right, bottom-center, or top-right. - **Color Selection:** Renders stamps in crisp black, litigation red, or attorney blue. - **Cover Exclusion:** Optional toggle to omit stamping on title or cover pages. - **Direct Download:** Saves the modified document as a new PDF file via local blob export.
### Concrete Document Production Example Suppose a litigation team prepares a 25-page discovery document:
1. **Upload:** User drops `deposition_contract.pdf` into the tool. 2. **Configuration:** Prefix set to `PLTF-`, starting number `101`, 6-digit zero padding, positioned at bottom-right in red. 3. **Application:** Page 1 receives `PLTF-000101`, page 2 receives `PLTF-000102`, and page 25 receives `PLTF-000125`. 4. **Export:** Clicking "Apply Bates Stamp & Download PDF" compiles the modified document locally, ready for immediate download.
### Privacy and Client-Side Execution All PDF parsing, text rendering, and document assembly execute 100% locally in your web browser using client-side JavaScript. Your confidential legal briefs, trade secrets, and privileged communications never leave your device.

Frequently Asked Questions
Is this Bates stamping tool compliant with legal confidentiality rules?
Yes. Because all processing executes locally in your browser memory via pdf-lib, no documents or privileged legal communications are ever transmitted over the internet.
Can I customize the starting number and zero padding for Bates stamps?
Yes. You can specify any positive starting integer and adjust zero-padding from 3 to 8 digits.
Can I stamp password-protected PDF files?
Encrypted or password-locked PDFs must be unlocked prior to uploading so the in-browser PDF parser can read the page dimensions.
