Add Dynamic Watermarks to PDFs Generated From Postscript Files With One Line

A few months ago, I was drowning in Postscript files. Every time I needed to convert them to PDF and slap a watermark on for security or branding? It was a mess. I had to jump through hoops, run multiple tools, and pray the formatting wouldn't break. And don't even get me started on batch jobs.

Then I stumbled on VeryDOC Postscript to PDF Converter Command Line.

Game. Changer.

The Fix I Wish I'd Found Sooner

I was searching for something lean and scriptable no bloat, no reliance on Ghostscript or any third-party printer drivers. Just raw, command-line power.

This tool checked every box.

You feed it your .ps or .eps files, and in a blink, you get crisp, fully searchable PDF files with watermarks, encryption, rotation, and even page bursts, all in one shot.

It doesn't need Acrobat, it doesn't need Ghostscript, and it doesn't care what printer drivers you've got.

Perfect for anyone who wants speed, control, and minimal dependencies.

Here's what made it a no-brainer

Let's break it down. I'll skip the fluff here's exactly how I've used it and why it's now glued into my workflow.

1. Dynamic Watermarks in One Line

This was the moment I knew I'd found a winner.

I could run:

lua
ps2pdf.exe -title "Confidential Report" -subject "Q2 Review" -author "Ops Team" input.ps output.pdf

And bam my PDF had all the metadata baked in and the watermark done.

Add a simple line like:

css
-embedjs "this.addWatermarkFromText({text: 'CONFIDENTIAL', rotation:45, fontSize:50});"

And you've got a dynamic watermark right there. No fiddling with layers or editing later.

2. Bulletproof Batch Conversion

I've got folders full of Postscript files generated from old systems.

I wrote a script that loops through them and runs:

sql
ps2pdf.exe -noempty -rotate 90 "C:\input_folder\*.ps" "C:\output_folder\"

Now they get converted, empty pages gone, and even rotated for proper viewing.

3. Built for Developers (But Non-Techies Can Hang Too)

Whether you're scripting in VB, Python, C#, Bash, or just running batch files, it slides right into your pipeline.

I've plugged it into a .NET app for automated PDF handling no hiccups, no guesswork. The docs are clean. The switches are logical. It just works.

Who Should Actually Care?

If you're in:

  • Print production

  • Legal or compliance teams

  • Government departments

  • Publishing

  • Data-heavy enterprises

and you're still manually converting or watermarking PDFs?

You're wasting hours.

This is for IT teams, ops leads, and anyone juggling Postscript outputs needing fast, consistent PDFs especially when security or metadata tagging is involved.

Why I'll Never Go Back to the Old Way

Before this, I'd tried other converters.

They were clunky.

Most needed Ghostscript or Acrobat installed. Others broke formatting. Some were so slow with large files that I'd leave them running overnight.

VeryDOC's tool?

  • Standalone no extra installs

  • Blazing fast

  • Batch ready

  • Powerful CLI options (rotate, encrypt, crop, watermark, etc.)

  • Small PDF output sizes

And it's reliable. Zero crashes. Zero formatting bugs.

Final Thoughts

If you're dealing with Postscript files and need them in PDF format fast, secure, and batch-ready this tool's a beast.

I'd highly recommend this to anyone who handles bulk document conversion.
