How to Bates Number a PDF Without Adobe — How to Do It Free Without Acrobat

How to Bates number a PDF without Adobe is a question that comes up constantly in law firms, paralegal teams, and legal operations — especially when someone is handed a production deadline and the office only has Acrobat Reader, not Acrobat Pro. Adobe’s Bates numbering feature is locked behind a Pro subscription that runs $29.99 per month. You don’t need it. Here are three free methods that work today.

What Is Bates Numbering?

Bates numbering stamps a unique sequential identifier on every page of a document. A typical Bates number combines a text prefix with a zero-padded number — for example, DEF000001, DEF000002, and so on. The prefix usually identifies the producing party (DEF for defendant, PLF for plaintiff) or the document set (EXHIBIT, BATES, a client matter number).

In litigation, Bates numbers make it possible to cite a specific page precisely: “See DEF000042.” Every page has one unique identifier, traceable across the entire production. Courts and opposing counsel expect it. Getting the format wrong — or using a tool that adds a watermark — creates problems.

Method 1: Use RapidTools in Your Browser (Fastest, Most Private)

This works on any device with a web browser. No software to install, no account to create, no watermark on the output.

1. Open any browser (Chrome, Safari, Firefox, Edge).
2. Go to rapidtools.online/bates-stamp-pdf.
3. Click the upload area or drag and drop your PDF.
4. Set your prefix (e.g. DEF, EXHIBIT, PLF).
5. Set your starting number and number of digits (e.g. starting at 1 with 6 digits gives you 000001).
6. Choose the position — bottom right is the legal convention; bottom left and bottom centre are also available.
7. Click Apply Bates Numbers. Processing happens entirely in your browser.
8. Click Download to save the stamped PDF.

The output is a standard PDF with the Bates stamp burned into each page as text — readable, searchable, and consistent. No watermark, no branding, no trial limitations.

Method 2: Microsoft Word — Convert, Stamp, Re-export

If your document started as a Word file — or if you need to add Bates numbers to something you can edit — Word has a header and footer system that can approximate Bates numbering before you export to PDF. This is a workaround, not a dedicated Bates tool, but it works for simple productions.

1. Open your document in Microsoft Word.
2. Go to Insert → Header & Footer → Edit Footer (or Edit Header, depending on your preferred stamp position).
3. Place your cursor where you want the stamp. Type your prefix (e.g. DEF).
4. Go to Insert → Field, select Page from the field list, and set the numeric format to a zero-padded number (e.g. 000001 by entering the format 000000).
5. Close the header/footer editor.
6. Go to File → Save As → PDF to export.

Limitations: Word’s page field always starts at 1 and cannot be offset to a mid-production starting number without a macro. If you need to start at page 247 (continuing a prior production), this method breaks down. It also only works on Word documents — not on PDFs you’ve received from opposing counsel or scanned originals. For those, use Method 1.

Best for: Internally drafted documents where you control the source file and need a quick stamp before sharing — not for formal discovery productions where precise numbering control is required.

Method 3: Command Line with pdftk (Power Users)

If you need to Bates number large batches of PDFs — hundreds or thousands of pages across multiple files — the command-line tool pdftk is the most efficient free option. It’s not point-and-click, but once set up it can process entire productions in seconds.

1. Install pdftk: sudo apt install pdftk (Linux) or brew install pdftk-java (Mac). Windows users can download the installer from pdflabs.com.
2. Stamp a single PDF with Bates numbers starting at 1:
   pdftk input.pdf burst output page_%04d.pdf
   This splits the PDF into individual pages, which you can then stamp and recombine.
3. For true Bates stamping with a prefix, use pdftk’s stamp feature with a pre-built stamp PDF, or combine it with a Python script using the reportlab library to generate per-page stamps programmatically.

Bates Numbering Conventions to Know

Before you stamp anything going to opposing counsel or a court, confirm these details:

• Prefix: Typically the producing party abbreviation (DEF, PLF) or matter number. Agree on the prefix with opposing counsel before production if possible.
• Digit count: Six digits (000001) is a common default. Use more if your production will exceed 999,999 pages.
• Starting number: If this is a supplemental production continuing from a prior batch, your starting number must pick up where the last production left off — not restart at 1.
• Position: Bottom right is the most common convention. Some courts or standing orders specify a required position — check before stamping.
• Confidentiality designations: Bates numbers go on the same page as any confidentiality stamp (CONFIDENTIAL, ATTORNEYS EYES ONLY). They are separate labels, not alternatives.
