How to Automate the Stamping Process for Large Volumes of PDFs with VeryPDF PDF Stamper Command Line

Meta Description:

Automate batch stamping of PDFs with text, images, and Bates numbers using VeryPDF PDF Stamper Command Lineideal for legal, admin, and enterprise workflows.

Every Friday, I dreaded the same thing…

Sifting through hundreds of contracts, invoices, and forms just to manually stamp them with dates, signatures, or “CONFIDENTIAL” labels.

How to Automate the Stamping Process for Large Volumes of PDFs with VeryPDF PDF Stamper Command Line

I used to print them out, stamp them, and scan them back in like it was still 2005.

Even when I went digital, I was still opening PDFs one by one and slapping watermarks or images on them using bulky, glitchy software that crashed half the time.

It wasn’t sustainable.

That’s when I stumbled upon VeryPDF PDF Stamper Command Line, and it changed the game.

This tool doesn’t just stamp PDFs. It automates everything.

I’m talking full-scale batch processing of hundreds of files at onceautomatically placing stamps like:

  • Logos

  • Signatures

  • Dates & timestamps

  • Bates numbers

  • Web links

  • Even custom watermarks

All with a few lines of code in the terminal.

If you’re in legal, finance, HR, publishing, or compliance, this tool is built for you.

I’ll walk you through exactly how I used it

The Problem

I needed to:

  • Stamp 250+ pages of contracts with company logo, a timestamp, and a confidential watermark

  • Apply Bates numbers to make tracking easier

  • Do it without manually touching each file

  • Encrypt the output files so nobody messes with them

The Setup

I used the command line. No GUI. No clicking around. Just raw, fast, reliable scripting.

Here’s one of my go-to commands:

pdfstamp.exe -PDFs "C:\contracts\*.pdf" -o "C:\stamped_output" -AI "logo.jpg" -AT "CONFIDENTIAL \d" -opacity50 -p3 -fs12 -c255 -encrypt -openpwd=myOpen123 -ownerpwd=mySecure456 -keylen=2 -encryption=3900

Let’s break that down:

  • -PDFs processes every PDF in the folder

  • -AI adds our logo

  • -AT inserts a “CONFIDENTIAL” stamp with today’s date

  • -opacity50 makes it semi-transparent

  • -encrypt locks the PDF with permissions

Boom. Done.

Standout Features That Actually Matter

1. Batch Processing with Wildcards

No drag-and-drop. Just tell it where the files are. Want to stamp 500 PDFs? Use *.pdf. Done.

2. Dynamic Stamping with Variables

You can inject stuff like:

  • \d for today’s date

  • \p for current page

  • \c for total pages

  • \B(0001000) for Bates numbering starting from 1000

3. Full Visual Control

You control:

  • Font size, colour, and rotation

  • Stamp position (header, footer, centre, diagonal)

  • Opacity for watermarks

  • Text or image layering (on top or below content)

4. Text, Image, Graphic & Web Link Support

Stamp in:

  • Logos

  • Signatures

  • URLs (yes, clickable ones)

  • Lines, shapes, and boxes

It’s insanely flexible.

How It Helped Me (No Fluff)

  • Saved 5+ hours/weekno more opening PDFs one by one

  • Reduced errorsBates numbering is always correct

  • Cleaner outputtransparent stamps that don’t cover text

  • Security lockedclients can view but not edit files

Other tools? Either they don’t support batch mode, crash under load, or give you zero layout control.

With VeryPDF PDF Stamper Command Line, I had complete control and speed.

Real Talk: Who Needs This?

If you…

  • Handle contracts, invoices, or confidential reports

  • Need to track documents via Bates numbers

  • Work in legal, accounting, government, or HR

  • Send docs with logos, footers, and disclaimers

  • Need to secure your PDFs after stamping

this is for you.

3. What’s the difference between text and image stamping?

Text stamping lets you add dynamic content like page numbers or dates. Image stamping is great for logos and signatures.

4. Can I control exactly where the stamp goes?

Totally. Header, footer, centre, cornersrotate it, layer it, fade it. Full control.
