How to Automate PDF Splitting Based on Keywords or Page Numbers Using Java CLI Tool

Meta Description:

Need to split PDFs by keywords or page ranges? Here’s how I automated it using VeryUtils Java PDF Toolkit CLI.

Every time I got a 200-page PDF report from legal, I groaned.

It wasn’t the contentit was the chaos.

How to Automate PDF Splitting Based on Keywords or Page Numbers Using Java CLI Tool

These monster PDFs were packed with contracts, appendices, and confidential notices all lumped together.

Sometimes I needed to extract pages by keyword (“Confidential Agreement”), other times by page intervals.

Doing it manually? Total time suck.

I tried Acrobat. Too slow. Too clunky. And forget about automation.

Then I found VeryUtils Java PDF Toolkit (jpdfkit) Command Line, and it changed everything.

Let me walk you through exactly how I use it to split PDFs automaticallybased on keywords or page numbersright from the command line.

What is the VeryUtils Java PDF Toolkit CLI?

It’s a no-frills, high-powered .jar tool that you run straight from the terminal.

Windows, Mac, Linuxit works on all of them.

Built for devs, sysadmins, and anyone who wants tight control over PDFs without the GUI fluff.

Here’s what stood out to me:

  • It’s command-line based (no GUI nonsense).

  • No need for Adobe anything.

  • Works in batch jobs, server environments, even cron jobs.

And yesit splits PDFs based on page ranges or custom logic like metadata or embedded keywords (with a bit of scripting).

Here’s How I Automated My PDF Splitting Workflow

1. Splitting by Page Numbers

Let’s say I have a 50-page PDF, and I want to split it every 10 pages.

One-liner:

bash
java -jar jpdfkit.jar bigfile.pdf burst output chunk_%%03d.pdf

Result:

You get 5 separate PDFs: chunk_001.pdf, chunk_002.pdf, etc.

Game-changer when working with repeating structures like invoices or purchase orders.

2. Splitting at a Specific Page

Need to split after, say, page 17?

bash
java -jar jpdfkit.jar report.pdf split_at 17 output part1.pdf part2.pdf

Boomtwo clean files.

I use this to separate executive summaries from technical annexes in board meeting decks.

3. Splitting by Keyword (The Slightly Hacky Way)

This one’s clever.

The tool doesn’t directly support keyword-based splitting, but here’s how I pulled it off:

Step-by-step:

  • Step 1: Extract all text to a temporary file.

bash
java -jar jpdfkit.jar report.pdf dump_data output report_meta.txt

  • Step 2: Use a small script (I use Python) to scan that text file for the page numbers containing your keyword.

  • Step 3: Split at those pages using the cat or split_at command.

Why this works:

Because once you know which pages contain the keyword, splitting becomes trivial.

Not plug-and-play, but highly doable.

I’ve scripted it into a reusable tool and saved hours of brain-numbing manual work.

Why This Tool Beats the Others

Acrobat?

Slow. No automation. Doesn’t scale.

Python Libraries like PyPDF2?

Cool for devs, but flaky with large, encrypted, or weirdly structured PDFs.

VeryUtils Java PDF Toolkit?

Rock-solid. Blazingly fast. CLI-friendly.

And it just works on massive files.

Here’s why I keep using it:

  • Handles encryption (input and output).

  • Doesn’t choke on 500+ page PDFs.

  • Works with wildcards (batch mode is sweet).

  • Easily slots into my automation scripts.

Who Should Use This?

If you’re:

  • A developer building document workflows

  • An IT admin handling internal report processing

  • A legal assistant tired of splitting docs manually

  • A finance pro dealing with bulk report breakdowns

…this tool is for you.

Final Thoughts

I’ve used this toolkit to slash PDF processing time by 90% in my daily routine.

Instead of spending 30 minutes slicing PDFs manually, it’s a 10-second script.

I set it, run it, and I’m done.

If you’re dealing with PDF workflows and want something that’s fast, reliable, and automation-readyVeryUtils Java PDF Toolkit CLI is your move.

I’d recommend it to anyone who processes large volumes of PDFs or needs automation badly.
