How to Add Password Protection When Converting PS to PDF for Legal Documents

Meta Description:

Need to secure sensitive legal PDFs? Learn how I added password protection using VeryDOC Postscript to PDF Converter Command Line.

Every legal firm I've worked with has the same fear

You're dealing with a ton of PostScript filesclient agreements, contracts, NDAsand at some point, one ends up in the wrong hands.

Boom. Breach. Panic.

A few months ago, I got a call from a buddy working at a mid-sized law firm. They had a batch of sensitive PS files they needed to convert to PDFbut they needed encryption, and they needed it yesterday.

Their team had been using some basic printer driver-based tool that worked fine until they needed actual security. That's when things started to fall apartno password support, zero batch capability, and way too slow.

I'd already been using VeryDOC Postscript to PDF Converter Command Line, so I set them up with it.

Game changer.

Why VeryDOC Postscript to PDF Converter Command Line?

No fluff herethis tool is all business.

It's built to convert PS and EPS files to PDFfast, secure, no Ghostscript dependencies, and none of the usual Windows printer headaches. It's command-line based, so it's perfect for legal teams that want to automate workflows or plug it into larger systems.

It runs like a beast on Windows, and if you're into scripting (BAT, VB, PowerShell, whatever), it's super easy to integrate.

But what really sold meand the legal teamis this: robust encryption.

Let's break it down.

Password Protection, Done Right

Here's how I locked down PDFs with 128-bit encryption using just a single command.

bash
CopyEdit
ps2pdf.exe -ownerpwd boss123 -openpwd client789 -keylen 2 -encryption 3900 input.ps output.pdf

What this command does:

• Sets an owner password (boss123) full control over the file.

• Sets a user password (client789) needed just to open the file.

• 128-bit encryption strong enough to keep data away from prying eyes.

• Disables permissions (3900) no printing, copying, editing.

You can go deeper with permissions too. Block printing, disallow content copying, or strip metadata entirely. It's all just flags in the command.

Batch Convert Legal Files? No Problem

I had another case where a client wanted to convert hundreds of PostScript files. No UI nonsense. Just script it and go.

VeryDOC's tool crushed it.

bash
CopyEdit
for %f in (*.ps) do ps2pdf.exe -ownerpwd secure -keylen 2 "%f" "%~nf.pdf"

That loop right there processed an entire legal archive in under 10 minutes.

And the output PDFs? Crisp, fully searchable in Adobe Reader, and secured.

Metadata? Sorted.

Another underrated feature?

You can embed document properties directly into the output. For legal docs, this is gold:

bash
CopyEdit
ps2pdf.exe -title
